He is very glad to not be that scout, with the little hint of a threat there. A shame he'd never been able to intimidate Hawke into behaving enough to let things fully heal. Then again, she'd at least had him nearby. The scout could be sent anywhere next, far from a healer.

"It is." Just Detlef, just a healer, please let her inquiries end there. Varric's help had certainly fleshed out his background, but there's no telling what resources Leliana has. The chances of her directly knowing more about Laysh than he does are slim, but that doesn't mean she doesn't have someone there.

He finishes the mixture up and carries it back to the scout, holding it out. "One mouthful at dusk and one at dawn. If you miss a dose, don't take two, come see me." Once that's handed off he comes back to the table and starts cleaning up, 'aided' by his hand being batted by a tiny black-and-white-spotted paw sneaking out of one of the canisters. "Or Adelaide, if I'm not currently available. I'll leave notes on the toxin and your name in case of that."

Chances are he'll be here, but there's no telling where he'll be needed. "Was there anything else the both of you needed?" Maybe they'll say no.
