I've posted before, that Dr Dylan Keogh is absolutely definitely an Aspie (In Casualty, UK). Though in his character depiction on the Casualty website, there's no mention of AS. I think they must be saving it for a really big storyline. For example, look at his low emotional intellegence at the moment with the lady who's interested in him, that has a dog, like him. She couldn't do more to say she wants to get to know him better - and then he turns around and says that it'll never work out. My bet is that they get it together, and then he finds he's got AS - up to now, he's undiagnosed. I think it is a sympathetic portrayal, and so I feel positive about it.
If anyone has views, love to hear them.
