EPISODE 4 – AVA
Ava hides her diagnosis of an STI from Felix as she manages everyone else’s problems except her own.
Synopsis
Ava is stressed because her English boyfriend is soon to arrive in Tenerife and none of her mates will help her prepare for his arrival. In truth, she’s stressed because he’s a germophobe and she hasn’t told him about her recent diagnosis of herpes – something which Cormac finds hilarious and bizarre. When Felix arrives, Ava maintains a sense of normality as best she can but the keeping-up-of-appearances is masking a deeper issue that Ava is looking after everyone else’s problems without considering her own.
