It's opaquely blue. 

"I think that's just a visualization. We'd probably have to actually stick our heads through."

Jenn considers it. "Are we going to have an argument if I ask you to keep a hold of me while I put my head through?"

"Yes."

"...Okay. Why do you think it should be you instead of me?"

"I was involved in more cracks, so might recognize if it's dangerous or where it is. If I get stuck I have my arm and can unstick myself more easily."

"...I'm sure there's a flaw in your logic. But it unfortunately makes sense. I'm still keeping a hold of you."

"Let's move, then," she says, and goes to kneel by the pool.

Jenn holds the back of her top, firmly enough that she isn't going to loose her grip, but loose enough that Bina can still move.

And Bina leans through.

It's dark, where she winds up.

But not pitch black. Dark in the way of the early morning. And there's someone moving. With a glowing-green watch.

She yanks back. Takes a deep breath.

She hasn't been noticed. Ira's attention is ahead of herself, on the edge of the pit. On Elizabeth.

She leans back into the between-times. Pauses. Says, "I need to check something," and leans back in, assuming Jenn lets her.

Jenn clicks her tongue, but allows it.

-And she exits at exactly the same moment as she had previously.

She returns back through the portal. "Time's not passing out there; I exited at the same moment both times. But also Ira's there, and it looks like it's just before she snuck up on Elizabeth, I'd be worried about changing something there..."

"Hard to change it without killing Elizabeth as well," Jenn says thoughtfully. "Or without us seeing ourselves..."

"I would strongly prefer we not kill me," she says, voice dry. "What about the other portals? I can see many directly below us, and the shine of even more."

"Not-Ant went through one of the ones directly below us. Let's...not go through that one."

"...I suspect I know where that one ended up. The not-Ant was - off, or something - at the bottom of the ramp when Ira was chasing me, and was about this size..."

"Okay then. I...think I know which island it went through." Jenn squints at the islands below them. "Probably."

There's a green thing far at the bottom, a distant many-armed spiraling being - 

Jenn jerks back, alarmed. "Gonna guess that's our space bug down there."

Bina peeks. "Yeah."

Elizabeth peeks. "Of all the genres I expected to be accurate it wasn't timetraveling scifi Lovecraft."
