Off he goes.

There are probably some entrances that aren't the main one – are any of them unmanned, can he get through past a smaller, subsidiary reception area instead?

Nnnnot really.

Well, there are employee doors...

Are they passcode locked, swipe-card locked, something like that…?

Swipe card, yeah.

But oh look there's also an emergency exit there.

… With a handle on the outside, one that he can open?

Not as such, no.

It is, however, somewhat old and doesn't actually close.

Oh, wonderful, he doesn't even have to worry about tripping any alarms.

Through it he goes, eyes open just briefly so he can see what's on the other side, and assuming it's clear he'll shut them.

Clear, yep.

He will run along!

Can he hear anyone saying ICU, detect any signs or such that he can quickly look at, guess where it might be from the life-support machine sounds…?

Yes he can. Super senses are very useful.

If he can see anything saying where the blood bank is, he'd rather go there first… But he takes note of the approximate direction of the ICU.

He can, actually! There are three, one per floor.

Oh, that's so convenient. He takes note of each of the positions, making very carefully sure not to stay in anyone's sight for more than like a tenth of a second and trying to stay out of them completely and staying out of the way of any security cameras that he can see by moving quickly… and then he knows more precisely where the ICU is and he goes back out the emergency door and back to the car.

"We good to go?"

"Yep! I know where the ICU and – three blood banks are, didn't go into any of them, there's an emergency exit that doesn't shut properly and I got in through that."

"Awesome." Out the car he goes.

"Preference for how you're carried? Or if I stop at each junction, or…?"

"Do whatever's most efficient."

"And I should presumably use my eyes, not echolocation this time."

"Yeah, I think that's best."

So he picks Sadde up and goes through the door, checking for people carefully.

Without Sadde, he is fast enough people aren't a problem. With Sadde, he might need to be strategic.

There are doors to cupboards and other rooms and routes he can tell have lots of people in them and gosh he hopes there are no security cameras that might be recording him oh well he'll probably cope.

He can backtrack as necessary, anyway, and going around the edge of the hospital to the side with the ICU should mean he doesn't come across as many people.

Yep, he will successfully reach it unmolested.

Then he'll place Sadde down slightly out of the way and – "Should I go scout for someone? Might be hard to find someone sleeping if I have to rush around with the both of us."
