I think Tel' s reaction was fair enough. He shouldn't have been involved and I'd imagine he probably hadn't wanted to be and at most had gone along to support Megan. Megan shouldn't have involved him and definitely should've chased up Dylan, IMO. I'd be annoyed if I was Dylan, both that he wasn't reminded and also that Tel was there.
I'm heavily involved with a boy with autism and I whole heartedly agree. Yes it's case by case. But I don't think Brooklyn shows any signs of autism at all. His speech seems ok when he hasn't got a dummy in, though it's a bit unclear likely because of the dummy. Little tantrums and aggression are NOT a trait of autism
He's literally mirroring his parents' behaviour and that's very clear to see.
