They're just in time to see Nate disappear through a chalk rectangle on the wall. 

Magic is great. 

"Well. We almost caught him." 

"Yep. Good try, though, and good reflexes, both of you," says Rain, watching the chalk portal disappear into a dull grey rectangle. "We've got them both in the long run, anyway, neither of them are particularly good at endurance. It just would have been nice to grab Nate and keep Yvette from vworping all over everywhere."

Kaldur nods. "That was quick thinking on your part, too." 

M'kel makes herself visible again.

"So what now?" 

Rain hums thoughtfully.

"I think we're coming at this from the wrong direction. Reacting instead of acting. Trying to catch Nate while he's got magic escape routes available would be like bashing our heads against the wall, so let's stop. Yvette needs to be on one side of the portals she opens. Which means that if we channel them into a known portal, one of our members," he looks at M'kel, and beams, "can wait hidden by it until it opens, sneak through to the other side, and grab our wayward witch. Thus shutting down the whole portal operation."

"Sounds like a plan! Shall we split up and look for chalk drawings? Oh—if I make a telepathic link between all three of us, we can coordinate our search," M'kel suggests.

"That'd be great! If Kaldur would also be comfortable with it? If not, you and I can be linked and talk and he and I can go together, so we can still coordinate."

"We can cover more ground if we separate. It is fine." 

"Great!" 

Hi! Testing, one two three—

It takes him a moment, but: Yes, I hear you. Rain?

Hi! I can hear you both! This is super convenient and has lots of neat tactical applications, I'm excited about it, because telepathy is great!

It's so convenient! I don't know how anyone manages without it. 

And now they can start hunting for portals drawn on the walls. 

They can!

While many are hidden, they're numerous enough that it's not very hard to find at least one. Finding all of them is a bit harder, but they don't actually need to do that; they just need to weed out enough so that the trapped portal comes into play. Rain makes a note that he and Kaldur should move away from where M'kel's hidden, so that Nate and Yvette think it's safe to send the speedster into the seemingly empty area.

It's really only a matter of time until they get a chance to spring their trap.

Eventually Nate takes the bait, dashing past a camouflaged M'kel and through the portal she's staking out. M'kel pounces, grabbing blindly for Yvette because Nate is too fast to catch.

Her hand latches onto an invisible arm. "Got you!" she sings out.

"But—what—that's—I've been out invisibled!" laughs Yvette.

M'kel becomes visible, also laughing. I got Yvette! she reports gleefully.

"Your invisibility is better! I only got you because I knew where you'd be." 

Yay!

Yvette decides that, yeah, she should probably drop her invisibility too, even if it'll last another couple of minutes on its own. Just out of politeness. She casts the quick counterspell that'll screw up the invisibility spell's thing, and summarily becomes visible.

"I don't know if I'd say better, mine doesn't last forever, requires actual materials, takes time to set up, and is apparently completely detectable to anyone accustomed to finding stuff with magic, so it seems like it's really more of a different set of trade-offs. How did you know I was—oh, you knew where I'd be because I need to be on one side of a portal. Oh. Oh of course that's an excellent way to find me, augh why didn't I think of that."

Is M'kel going to stop laughing any time soon? Probably not. 

"It was Rain's idea!"

Rain is so good. She tells him so.

Thanks!!

He also thinks M'kel is pretty great, but he sort of feels like that's the kind of thing that shouldn't be broadcasted to Kaldur as well as to M'kel, so he just lets that bubble happily in the back of his mind instead of directly stating it over the link. He hopes she can notice.

"Of course it was. I've had a brother for three days and he's already foiling my plans, augh."

Heee.

"Now you can help us foil Nate and Robin's plans! We've been using my telepathy to coordinate; can I add you to the mental link?" 

"Oh! Uh, yyyes if you only get things I mean to send? Will I not, uh, accidentally bleed whatever I'm thinking to everyone else in the link?"

"I've been using telepathy since I was a baby," M'kel says, "so I'm not sure how hard it is to learn, but Kaldur and Rain haven't shared anything accidentally yet? And I'm not looking for things you don't send, that would be rude."
