"Sure," Gerard shrugged carefully, wincing as the skin across his shoulders pulled tight. "We stopped you once, right? And now we know what to expect, it's fine." He still braced himself when William bolted the draught -- he would have foregone potions himself, but Bob had had formal training, whereas Gerard had more of a battlefield, 'make-do-with-what-you-have' approach. Gerard was more than willing to defer to him on this front.
And sure enough, William showed a marked lack of murderous rage and Gerard was able to slump in relief. William started rubbing in more aloe, talking a bit dreamily about Veela bloodlines. Much, much better, enough that Gerard could relax a bit and compose a terse Patronus message and send it skittering off along the hallway. Then he pondered what William had meant by 'mate for life.' He had an almost overwhelming urge to send a follow-up Patronus to Nate and flail excitedly, because they were so right with their theories. Gabe and William were so totally made for each other.
Except, well, there was the Healer-patient confidentiality thing. And also said 'mate' was off hiding in a bedroom and playing chess with a cat rather than helping reassure William, so Gerard wasn't entirely sold on the 'for life' thing at the moment.
