We鈥檙e always happy 鈥 okay, almost always 鈥 to see some new faces on Grey鈥檚 Anatomy. (Case in point: the swoon-worthy Dr. Nick Mars, played by former Felicity star Scott Speedman.) But we love a good blast from the past, too 鈥 hi, Teddy! 鈥 and the people behind the scenes are about to hit us with a big one.

According to Entertainment Weekly, the April 26 episode of Grey鈥檚 will feature the return of former Seattle Grace staffer Olivia Harper (Sarah Utterback). Longtime fans of the medical drama will remember Olivia from the first six seasons of the show as a nurse at Seattle Grace who was let go amid layoffs prior to the merger with Mercy West Medical Center.

Before she left, though, Olivia made quite an impression. She not only handled her fair share of medical emergencies and life-saving situations, but she also faced her own health issue during a syphilis outbreak. After contracting the STI from a casual hookup with Dr. Alex Karev (Justin Chambers), she inadvertently passed it on to Dr. George O鈥橫alley (T.R. Knight) when they began a relationship.

According to EW, both Alex and his newly minted fianc茅e, Dr. Jo Wilson (Camilla Luddington), are 鈥渢hrown for a loop鈥 when Olivia returns to the hospital with her son.

We don鈥檛 have any other details about the nature of her visit to Grey Sloan Memorial Hospital, but knowing Grey鈥檚, it鈥檒l be must-watch TV.

Grey鈥檚 Anatomy airs Thursdays at 8pm on ABC.
