So remember when Damien first started as a debt collector. He was met with harsh words and even got a smack across the face from some bloke. When he met Neasa for the first time, she tried the softly approach and kissed the begger. Ever since, he has been wary of the girl and he when he finds out she is his next door neighbour, he starts to panic a little. I think it's because he knows she's a lot better looking then his wife, he just doesn't want to admit it.
