Just watched tonights episode, I thought the Robron stuff was OK.
Adam being an idiot, Vic actually slightly more supportive although offering a bed at hers when PD is there not very wise.

heartbroken and lost,

being strong/firm/hard, all the things he needs to be to get well especially in the pub with everyone around, in The Mill he is clearly bothered as when

said I am so sorry

said he was as well.
Solution - get rid of PD and I think they would be back together - that is the problem,

little glance to HER said it all.
