ABCs third-season premiere of Station 19 in its new 8 PM slot in a two-hour crossover with its flagship Greys Anatomy gave thee network the two most watched and top-rated shows in primetime Thursday.

With Greys showrunner Krista Vernoff now in charge of both shows and three more crossovers in the works this season under Vernoffs unified command, Station 19 (1.2 rating in the adults 18-49 demographic, 6.98 million viewers), now at 8 PM, returned as the nights most-watched program, gaining four-tenths in the demo from its Season 2 finale in May.

It was followed by Greys (1.4, 6.65M), settling nicely into its new slot. Its demo number was even with Greys fall finale back on November 21.

In an interview with Deadline in November, Vernoff said the two shows will interconnect every few episodes. We dont want to do it every week, we dont want to create a mold, we dont want to fall into any kind of pattern, we dont want people to ever know what to expect, she said.
