Glad you like the Monday postings! *g* Smut to kick off the week well.
The relationship between Teddy and Remus is, of course, meant to be uncomfortable, so I'd be worried if it weren't bothering you (and other readers). For me, I think the appeal is partly that it's a good vehicle to explore that theme of discovery, and also boundaries (boundaries and marginalization are themes I've worked with a lot over the years) - there are so many potential problems inherent to the pairing, you know?
You're right, Remus is very much rationalizing things. Teddy simply doesn't think about the possible consequences - he knows them, but they're not real to him - it's that "invincible adolescent" attitude. But Remus... Remus tries to justify ways he can have what he desires, and not inconsequentially make other people happy.
