Eshi edges out of the thing's way-- when she hears the crash of the beast tackling someone to the floor, she rushes into the foyer.  She knows that the thing following her is probably exceptionally dangerous, but she doesn't really care-- she can only act out of instinct and whips the sword overhead and rushes in to stab the beast that pins the paladin down.  (please tell me it's denied its dex bonus to AC so I can feebly backstab?)
