As the lizard went for Colin, Megaera lept clear - sticking it in the tongue hadn't done as much as she'd hoped, and now it had flat-out eaten one of the group, whole!

If she was correct, Colin had... Maybe a minute to live, what with the stomach acid and such. If they could slay the beast and stop it's stomach muscles...

Then, Zuko was leaping onto the creature's back, angling to strike it directly in the eyes. Megaera, for her part, simply dove right back in front of the beast, raising her sword. As soon as its mouth opened - whether in a scream of pain or to bite wildly at her - she'd try to drive the sword directly into the roof of its mouth.

Insanely risky, but keeping the beast's attention on her was ideal. Especially since the right strike might just give Colin his escape.
