*nods* You're right that Teddy is basically thinking of Remus as something like a boyfriend or lover... not consciously, perhaps, but that is how he's responding. So yes, Remus's reaction -- to cut the physical contact -- also works to reinforce his role as teacher there, since as a father he's a fairly touchy-feely sort.
Maybe Remus always asking him if he wanted to do such and such a thing and encouraging Teddy to refuse if he didn't want to do something, helped Teddy make the correct decision for himself.
Yes, I think so. If Remus knew about what Teddy was doing here, I think he'd be pleased that Teddy had learned some valuable lessons already.
Glad you're enjoying Andrew! *does happy dance* Sam, well, there is a canonical Stubby Boardman, but Andrew is a completely original character and OCs are always harder to get readers to respond to. So hurrah! Andrew will be showing up again, no fear... although of course I shan't give away future plot... *g* Thank you for the lovely comments!
