I guess they might have been afraid of letting fans think that might happen again. I only saw one clip they were in -- I think she told him about the abortion and he didn't get upset (which he credited to therapy). Was that it?
As for Christian, I have always felt the character has been all over the place, although that hasn't been as bad lately. The lack of character interaction is something which has hurt Eastenders a lot in recent years -- I have to admit I'm surprised they haven't had him in any scenes lately with the Beales, even as other characters are interacting more. Perhaps this is down to John Partidge's busy schedule. Anyway, I think one problem is that the people running the show had ideas in their head which did not necessarily translate onscreen. I believe that the scene of Christian coaching Amira on how to please Syed was supposed to be selfless and tragic. I don't think there was any nasty undercurrent intended. I think it just didn't work. Since Syed and Christian properly got together I think their relationship has been more believable and they are finally dealing with issues about their lives, so I hope that continues.
On the one hand I can see where they might be getting less airtime because the show doesn't know what to do with them but I also think less airtime is needed because the entire family (aside from Tamwar) was significantly damaged in the first half of this year. I just hope the show can overcome this because before that, Zainab and Masood were great characters.
I think you don't try to find a favorite, they find you.
For a long time Eastenders had very rich, complicated characters, they jumped off the screen -- they had someone for everyone. In recent years the show has been more flat, with stories that are more about what they are supposed to be than what they actually are. For instance, there were over two years where I never believed any love between Jack and Ronnie, yet they were pushed together because the show wanted us to think they were a supercouple.
I think that the telling not showing aspect is decreasing, the characters are becoming more lifelike, and I notice more and more of characters sitting and talking or characters just sitting and we can imagine what they are going through. Small little moments that, if you want, can stay with you. That's what Eastenders was, and what it hopefully may be again. That's also where you find a favorite.
My favorites on the show now are Max, Dot, Ian, Denise, Zainab, Patrick.
