How do you know Todd's thought processes? Many times, situations like that will happen with Aspies, but for different reasons. If Todd had Asperger's Syndrome, and he did things like that often, then probably most of the time he would not understand that Mike wanted to leave because Mike wasn't direct enough (in Mike's case, probably out of fear of Todd). If someone asks someone with Asperger's Syndrome if they can leave now (or if they want to leave now), the person with Aspgerger's Syndrome might not understand that the person really wants, and needs, to LEAVE NOW. A lot of times, people with Asperger's Syndrome are confused about situations like this, but the NTs don't understand, and they assume that the Aspies knew what they were doing. In a way, it's like personification in that NTs ascribe NT thought processes to Aspies.
There is a chance that, even as an Aspie, Todd knew that he was being mean and did it anyway, but that is not "normal with Aspies".
If, on the other hand, Todd wasn't an Aspie, he may or may not have known what he was doing, and you should talk to him about it.
