While most of Grey’s Anatomy takes place at Grey Sloan Memorial Hospital, sometimes the doctors venture off into the world. Joe’s Pub is the most frequent hangout — though it’s been featured less in recent seasons — and of course, we see their homes, too. In an upcoming episode, at least one doctor is going somewhere new, though, and it sounds exciting.

On October 22 at around 11 p.m. PT, Sara Ramirez (Callie Torres) tweeted that she was location-jumping to a place called the Martini. And she wasn’t alone.

“On to the last set up for the night. It is called the Martini! I am here with hardest working crew and two awesome guest stars!” she tweeted. Hmm, two guest stars? There have been no rumblings of big casting news, so we have a feeling they are people we’ve already met: Callie’s parents.

Last we saw Callie’s family, it was when her father, Carlos Torres, came to her and Arizona’s wedding in Season 7. Unfortunately, her mother, Lucia Torres (Gina Gallego), did not come with him. Notably, we recently found out that Carlos (Hector Elizondo) will return in an upcoming episode, so could he be bringing his wife with him? Will Lucia finally accept Callie for who she is? Fingers crossed.

A quick search of Seattle hotspots called “Martini” didn’t come up with anything, but it is likely just a fictional place. Perhaps they all go for a drink or dinner and talk out their issues. Considering that she and Arizona are split up right now, it will definitely be an intense conversation.
