The Trauma website says it's repeated on BBC3 on Mondays at 9pm. It lies!
Have just trawled through the Guardian Guide and double-checked with Sky's onscreen listing and have come up with the following - all on BBC3:
Sun 18 11pm
Mon 19 3.25am
Wed 21 10.20pm
Thu 22 2.15am
In fact it is also repeated IMMEDIATELY after the programme on Thursdays - BBC1 8pm, BBC3 9pm (and again at 1.25am on Fridays). Why they couldn't tell us that on the website I have no idea.
Anyway lots of chances to see bells's lovely family again!
