Okay, I read this a million years ago, and I'm going to get caught up on this fic today, so it's high time I commented here.
This one is so full of complexity it is hard to know where to start! Remus telling Teddy that he needs to stop seems like a very very good idea at this point, especially as their individual relationships are both taking off, and their father-son relationship is getting completely off-track, according to me, and into majorly dangerous territory. So I was happy to see dear reasonable Remus have that moment.
Also, Andrew and his overeager self is just too cute, and it is fun to see how confident Teddy is due to his training...eek! Does that mean it seems to be a good idea?? No no no.
