Oh. Billy remembered that day...those words, and what'd asked of Soldier. He looked unsure, doubting himself, along with his interpretation of what Soldier was saying.

"...can I try a spell?" he asked, gesturing faintly with his hands. It didn't seem right to not at least try to ask for Soldier's consent, given everything that had been done to his mind over the centuries against his will. That and he didn't want to trigger an offensive response if he just started in without warning.
