I think that most people are aware that I am a Tachel fan and I have been before they even got together. Like a lot of people have said in the past, the show needs a strong, mature couple and they are pretty much it at the moment. They are good for each other and they do seem to work. I think their relationship started off being written really well but then the powers that be didn't allow us to get 'involved' in the relationship which caused a lot of people to not 'believe' in it. The engagement was probably slightly rushed and they were getting one episode storylines which didn't help but they have come back a bit more strongly with the episodes since the vasectomy reversal. Also, I think the episodes after the OC showed how much Rachel loved Tony. We knew how much Tony loved her but I think that showed how strong their relationship was even if we hadn't seen much evidence of it. (I will just gloss over the Bridget 'blip' )
As for Tony being timid... I can see your point.. there have been times when it would have been nice if he asserted himself a bit more but I feel that maybe he isn't being given the best 'deal' by the writers at the moment.... or the editors! It does seem that there have been some scenes edited out recently that have made us miss out on some crucial scenes. I could be wrong but in the episode after Joe died, where Tony and Rachel didn't have a scene until the end, it did seem that there was something missing. I think we missed a scene where they went home and had an argument/disagreement after seeing Dane as Tony's conversation in the bar with Alf didn't make a lot of sense.
Going back to Tony being timid.... I think that there were a couple of occasions when he was with Beth that he just went along with her instead of making a stance so I don't think it is anything new. A couple of times Beth asked him to support her when he wasn't really sure what she was doing was right but he still supported her. In Martha's words..... "He's a good man..... a caring, loving guy"
But yeah AngryHotDad is good too!!
