So we have to assume that we were slightly deceived by the ABC promos, and that by "the crossover event begins this thursday," they actually meant "begins next thursday," because otherwise whatever it was that we spent two hours of our lives on last night, it wasn't a crossover -- event or otherwise. Actually, maybe that's too harsh. We suppose there was, technically speaking, "crossover." Are you ready? Here it is...

Yes, indeed. A phone call. And actually, even that was a bit of a stretch since no character from either show actually appeared on the other, nor did we actually hear Addison's or Derek's voices on the other end of the line to legitimize this charade. Presumably, the scenes shown in the promos in which Derek and Addison are actually in the room together will make next week's episode the actual crossover, and this week's episode nothing more than a hoax.
