Medical Drama: Casualty 8.10pm BBC1
The usual welter of disparate cases faces the Holby staff this week, from a young man with serious injuries after being trapped under a car, to a girl fighting for her life after an allergic reaction.
As usual, though, the medical personnel are more wrapped up in their own emotional predicaments. Daft Bex (Sarah Manners) is moping around after ex-boyfriend Pete, and attends a Valentine's Day ball in the hope of erasing him from her memory. Unfortunately, as luck would have it, she bumps into Pete on the dance floor (as you do). The evening doesn't end happily.
Abs, meanwhile, continues to needle dim Ellen, who's up to her ears in trouble, though he takes a little time to meddle in a pregnant teenager's personal life, jumping to the wrong conclusion in the process.
