He can't really explain it to them. He will pocket some chalk, and wait.

People soon shift to cleanup. Lots of moving around and talking.

...Actually, a few minutes into this if he's looking outside at all, he sees a few cops acting kind of shifty, hiding away the guns and yellow exploding objects from the three lizards just outside the school. It looks like they were considering the bodies too but settled for some bits and pieces of them after realizing they are over 120 kilos each.

...he can't really go confront them because they will not understand the question and he will not understand the answer. Can he point them out to whoever seems most on the ball of the folks who Aren't Doing That?

Commisar Belov Sheriniko has arrived by now and, actually, wholeheartedly approves of this looting. The language barrier may leave his impromptu speech on the selfishness of the Xenonauts, and the need to secure alien materials for the USSR instead of an untrustworthy international organization, landing poorly, though.

It's around this time when that same squad of silver-armor troopers from before comes back down the street, plus a gaggle of technicians in pale blue garments and that big X emblem.

Commisar Sheriniko sets his jaw and plants himself firmly between them and the alien bodies.

...wow Blai really doesn't have a guess about what to do if there's internecine human fighting, please don't.

They already have Sebillian bodies, the weapons are probably already on a truck to some blacksite, so they would mostly serve as additional data, and that is... Not worth causing an Incident over.

There's a brief standoff that concludes with silver-armor-leader gesturing towards Blai with a med kit to please follow, and the Commissar trying to indicate that he could go or he could stay. He doesn't have to go with them.

The med kit is promising?? He really doesn't have a lot to go on here. He takes the chalk out of his pocket and makes a drawing gesture, not actually touching the ground, and then touches his holy symbol and points at the kit, and maybe they'll piece it together.

They smile and nod at least. Someone has prepared a photo of a field hospital to show him.

The photo is kind of more confusing than the live scry but okay! Is the field hospital the sort of place one can chalk out a sixty foot diameter circle.

Maybe if you moved a bunch of the cots?

A big truck rolls up. Silver armor folks climb in to two long rows of seats in the back and gesture for him to do the same.

That's sure an object. He will embark upon the object.

The object goes to a field hospital! Everyone piles out.

The ratio of injured survivors to dead is low but there do exist some of the former.

A blue shirt person has a whiteboard, markers, and one of the brand new tablet devices reverse engineered from alien electronics, set currently to play images and videos from a small gallery, is waiting here. There's also a woman here without the same uniform, but to whom everyone seems to be deferring. She watches Blai but doesn't say anything.

The blueshirt demonstrates the marker and eraser by drawing a line, and offers it and the whiteboard to Blai. Then he pulls up a before/after pic of a nasty chest burn before and after six days in the regen tank. It's mostly just a scar by then.

Well, magic healing doesn't leave scars but that's pretty good for if they don't have that and are working with, what, bandages and herbs or something.

Blai draws a stick figure with the sword-and-sun in the middle of a circle full of people - are any of these markers red? Red-marked people - and then another circle the same but with the people no longer red-marked. Though the process will not actually clean blood off of them he hopes the gist is clear.

Nod, nod.

So it's- 

-The drawing program on this thing sucks. He pages through the digitized encyclopedia and eventually finds an image of one of those Tesla Spheres and manages to draw a very bad stick figure over that. And then a frisbee and the same stick figure over it. He points to the sphere, questioningly.

...tentative slow nod, yes, channeling is a sphere.

Wow, fascinating. The sword and sun is the source of the effect...? That seems impossible but so did the alien psionics, and teleporting, and antigravity, and fusion tech, and supermaterials... Uh, right. He starts sketching something-

The woman says something in a stern tone.

...He produces a sketch of Blai drawing a circle with chalk. Yes?

Yes.

Nod, nod. How about some numbers, in the form of tally marks. One, two, three, make sense? 

He gestures at the previous whiteboard scene of Blai healing people. One time? Two times? More?

Blai holds up two fingers then puts one down.

Concerned foreign language discussion...

They'll be distracted for a little bit trying to format questions into the form of probably confusing pictures; They gesture him to draw the circle in the meanwhile.

Eventually: They have a slideshow of options around the healing. Is it more like:

Blai is doing the healing by... Thinking really hard? And getting tired?

The dagger-and-sun has some number of heals inside it, and they get used up?

The dagger-and-sun has liquid in it, going down in increments as he heals?

Also, sketches of Blai going with the silver-armor-people and then people watching him heal, pointing weird devices at him and healing subjects, and maybe eventually making a thing that heals like he does, or maybe more people who heal like he does- Or, that seems to be the gist of that sequence of images, it's kind of hard to keep track of context with wordless pictures.

He draws a circle.

He guesses that of these options it's more like the second thing?

He is going to express uncertain skepticism about the sketch sequence.

They measure the circle and then start packing people into it. (A bunch of people are moving around doing things in the background too; Most notably: Helicopters landing and taking off, loot collecting and sorting, loved ones visiting injured people, and more injured showing up. There's a minor incident where someone wants to get into the area and the X-emblem people don't want to let them in, and he complains loudly and unceasingly off at the perimeter.)

Here's a bunch of injured people packed into a circle! Reasonably efficiently for a first attempt.

Can Blai figure out why that guy isn't allowed in, is he just less injured than everyone who is?

The person being kept out is a local, and the point of contention seems to be the device with a big glass lens on front that he is carrying. They'd let him in without that!

Seems likely to be a legit sort of thing then. Blai checks that nobody's obviously leaving space another person could fit in and then takes hold of his symbol and channels.
