On top of his role as Ford on Shameless, Richard Flood has had recurring roles in Red Rock and Crossing Lines. We look forward to seeing what he brings to the mounting hospital war in the sixteenth season of ABC’s popular medical drama, as the staff of Grey Sloan Memorial grows in opposition to the new staff at Pac North.

The fifth episode of Grey’s Anatomy season 16 will air this Thursday, October 24, at 8pm ET, as part of ABC’s #TGIT lineup. Be sure to check Hypable for our weekly reviews of the new episodes.
