"Many of us discussed earlier the ramifications - not to mention WTFness - of Ty wanting to meet with Allison McDaniel"
I get that there are serious legal ramifications to this, and that it is unlikely that any doctor in his right might would pursue this type of relationship. Yet I was still rooting for it as a reader; it is after all fiction. How likely is it that a brain surgeon would get an extremely rare brain tumor? The odds are against it, yet this type of thing happens on just about every medical drama. Why? Because it's dramatic. I thought the same thing with the potential relationship with Ty and Allison. What's between them is already so loaded, it would be an against-all-odds romance. But there were a few things that made me ship for these two. First of all, Ty is a brain surgeon--a doctor. Being in a field where I sometimes work in doctor's offices and hospitals, I can attest to the fact that doctors--in general, of course--tend to be pricks. Especially surgeons. If he is surrounded by these egomaniacs, no wonder he sees something attractive about her. I think he was terribly moved by the fact that in her darkest moment, she showed concern for him. That would prove that she is a good person, and maybe that in itself would supersede his concerns about how appropriate the contact would be. Particularly if he were in a dark place of his own. Secondly, on a spiritual level, tragedies like that do bind people together in inexplicable ways. So even though we all bristle at the legal and emotional ramifications, I think it could be a solid romance if written right.
