S1, E4: The gang head to a Thai beach for some R and R and a Full Moon Party. But Dylan’s ex, Lauren turns up to rekindle their relationship, and is soon dictating the gang’s activities. Hurt by how quickly Dylan has forgotten about her, Ashley spends some quality time with Sean. Sean’s hopeful this might lead to something more until Ashley reveals that she and Dylan slept together in Vietnam. May gets food-poisoning and demands that Ash stay to take care of her instead of going to the alternative, very much not Full Moon party that Lauren is taking them to. Ash gives her a sedative to get her off her back and avoid being her nurse, but when she gets back later she discovers they’ve been robbed. Lauren’s alternative party is a total bust. Greg makes a break for it and heads for the real Full Moon Party, but it’s not the same as he remembers it. Nothing is. Dylan’s conflicted about Lauren, but a moment of perfect romance presents itself and he’s overwhelmed by it and proposes.
