Tests

Hungover and worse for wear, Caroline is feeling the effects of the party the night before, which she still can't completely remember. When her kissing exploits come back to her, she is forced to trawl the hospital to apologise to everyone she kissed and insist it meant nothing – even to Mac, who of course it meant everything with.
Meanwhile both Harriet and Joanna think that they are pregnant and are soon taking trips to the path lab. While Statham is ecstatic at the prospect of becoming a father, Joanna is far from thrilled with the positive result – until it turns out the results were mixed up with Harriet – leaving Harriet the depressed one and ending with Joanna breaking up with Statham.
Elsewhere in the hospital Mac secretly has an interview for a better job, while Martin continues his quest to further his own career by taking his doctor's exam yet again.
