Yet another doctor will be in!

Amber Tamblyn will reprise her role as Dr. Martha Masters for the series finale of House, the actress told reporters Friday night at a red carpet event celebrating the series.

Olivia Wilde checks back in to House for series finale

Masters was introduced early in Season 7 as a replacement for Thirteen (Olivia Wilde, who is also expected to return in the finale). Tamblyn, however, was mum on the circumstances in which Masters will return for the swan song, joking, "House [Hugh Laurie] pulls his face off, and it's me. That's what it is. All along it was Martha."

Who else would you like to see return for the series finale, airing May 21 on Fox?
