I love each of these scenes like WHOA. Snape, being all *prim* and specifying the waterfowl by more technical names, and simultaneously managing to insinuate that Lupin is a loon. LOL! And Remus, trying to get Snape to relax and go for a silly duck-boat tour and enjoy a vacation. Good thing they will have many years together!
And Snape unwinding, relaxed on the couch at the Weasleys, finally having a circle of friends. ♥ ♥ ♥
