Hats off to the Casualty writers: this new series seems to be all about unlikely double acts and it’s absolutely inspired.

First off there’s Iain and Lily, the most mismatched but compelling ED romance in ages. Tonight, Iain pushes his new girlfriend to tell the rest of the department they’re together, but is she ready to go public?

Then there are the ridiculously incompatible friends David and Dylan, whose brilliant bromance is hilarious to watch.

It’s a serious time for them tonight, though, as they reunite Sanosi with his uncle and don’t get the happy ending they wanted.

Finally, there’s Connie’s newfound maternal instinct towards Ethan, and this week she reveals big
plans for his future…
