[If Teddy still has some misgivings or doubts about what happened or how they were affected - or worse, how Billy really felt - then that's something he definitely needs to deal with first. Even if it means delaying their bedroom experimentation for a while; it's a small price to pay for Teddy's mental well-being.]
