Yeah Sean is way too overprotective if he thinks Bradley is a problem. What he could have done to upset him is anyone's guess. Unless he immediately finds out about the baby and that's why he doesn't like him, which is nonsense because it could happen to anybody.
Anyway I am really excited as to the outcome of this storyline. On the one hand I don't want Bradley and Stacey to split up, but a bit of drama might do them good, as long as they work things out.
