[Armin tries not to think about how it could be any of their pokemon in those cages. That'll just make him think of poor Ambrose. He doubts he is down here. After all, those Team Rocket members had fled away from the basement, not towards it.]

Let me try. Though it is probably best if you don't hold it.

[He wouldn't Aurora to accidentally miss and freeze off a couple of Bertolt's fingers.

With that said, he turns to his little --well, maybe not so little-- dratini, stroking along her fin-like ears.]

I know we've never tried this before, but could you try and use an ice beam on that lock?

[Aurora peers at Armin, glances at Juniper, and then, encouraged by what she sees there, she blasts the lock with a shot of ice. It's not enough to freeze it entirely, but it is a good start.]

That's it. Keep going.
