"can not wait to learn more about Alex =)I think the PP part of the last crossover was a good ep, there wasn't enough Addison in the GA part, she was hardly there, it was a bit pointless!I think the two previous crossovers were great eps.I think it is inevitable that they will cross paths again, especially now Derek's sister is in PP, it would be stupid to ignore it, i guess we will know more when we see" . . .
