I started reading your fic today and finished all parts just now. I love how you dealt with the injuries and recovery of Remus and Severus. It's also seems logical that Tonks would have had an affair with someone and "see what she wanted to see" as Severus put it. I think Tonks was a bit off in the head concerning Remus, and I agree with Remus that she still should have known it wasn't him. Tonks would've had to been blind drunk not to knnow. I guess you can tell I am not a Tonks fan ;P
I'm looking forward to your next chapter and hoping we don't have to wait too long :)
