This relationship with Mel and Phil is nothing short of disgusting to me. I can’t fathom that Philip could possibly ‘love’ Mel that quickly. And I don’t believe for a minute that she ‘loves’ him either. In fact, I can’t find any possible reasoning for this proposal. It’s all a sham AFAIC.
As someone else mentioned, the best thing they could do with this fiasco would be to make it a dream sequence.
