Grey's Anatomystar Ellen Pompeo says 'the show must go on' but she'll 'be back to visit'

Pompeo’s latest Instagram post raises questions about her involvement in the future of the series.

And now, Pompeo has taken to Instagram for what feels like a punch in of goodbye.

Through it all….none of it …would have been possible without the best fans in the world.

You all are RIDERS and you all have made the ride so fun and ICONIC!!

I love you madly and appreciate you right back.

(Merediths' mother suffered from Alzheimers in the drama’s early seasons.)

Should the show get renewed for season 20, would Pompeo return as a series regular?

Either way, Meredith’s big move marks the end of an era for the series.

Grey’s Anatomyairs Thursdays at 8 p.m. ET/PT on ABC.
