I wish this Kathy & Buster affair hadn't happened - or been purely an emotional thing.
Kathy would never sleep with another woman's man in their bed. At least she recognises it's wrong but still...
I'm not saying she'd never have an affair as I think in the right circumstances, anyone could. Buster's with a partner who shows him little affection, while Kathy's just come out of a horrific relationship, the two of them finding comfort in each other's company I don't find hard to believe, but this and shagging in the kitchen at Beales is too seedy for Kathy.
