I have never warmed to Dr Alex, not sure why he's so popular. Yes, he was good, for eg, when he was dealing with Ellie's outburst, but I think he's emotionally thick, for all his apparent brains. It is all about him and his needs dressed up in courteous language.
I remember when he was sitting at the pool with Grace I think, and he was asking her about her family and she was very hesitant, saying that she didn't really have a close family and he just leapt on in there going on about his mother and father saying how he had to call them all the time or something. Grace looked lost frankly, he was spectacularly insensitive there I thought. I think she had something to say there and he just bulldozed over the top of it. Not keen.
