They've only interacted once before, and though it had been favorable, it's difficult to gauge someone's true nature in such a short time. He also doesn't know if he can trust Eustace in return, but Thoma has always had fairly good instincts when it comes to judging others and can usually sniff out a lie.

However, something tells him right now that he'll have to be the one to surrender first if he plans on getting what he wants. It's a gamble, but Thoma nods and rolls off Eustace before dropping his spear, letting it clatter noisily on the cobble stones. He then takes a step back, hands lifted to show he's about as unarmed as he can be. It's a bit harder to relinquish his pyromancy, so this will have to do. ]

[ Many would call him very stupid ...including his lord, and maybe Thoma is being too soft about this, but he sees no other way out of this that won't end with someone dying –either him, Eustace, or the Veneran rebel. ]
