I watch both but I'm suddenly confused as to which I'm supposed to watch first?!
I watched S19 S4 Ep 6 last night and then GA S17 Ep 6 (well half of it and then went to sleep).
There was a huge crossover but it was clear when watching Greys that the events of the Station 19 episode Id just watched hadn't happened yet!
I thought we were supposed to watch Station 19 first?
I know people complain about the crossovers but I don't mind Station 19, I just want them to be in the right order!
