I would be super delighted for that starting-off point of their CR! The client-worker stuff that is. No need for cheating/drama, and William would be quite at Anders having his SO back.

Although maybe we could do both! I'm sure there's turnover with doctors and such, it wouldn't be that odd for William to need to find someone new for his checkups. If Anders wouldn't find it weird after they'd had sex before, then William wouldn't either.
