2. Liz’s parents’ Gillian and Peter are still unimpressed with Seb.
Liz and Seb are reluctant to leave each other. Seb is proud that he's learned not to push people away, but is worried Liz doesn't feel the same way he does. Liz is concerned Seb just got caught up in the "experiment" and might not be that interested in her.
Liz tells her parents, Gillian and Peter, she's worried he's not going to make grown-up decisions, and that he might not be as focused as she needs. Peter thinks he might not have a good sense of self. He advises her that she needs to decide if she wants to be with him in the real world after the honeymoon period. Her mum says she'll be behind her no matter what decision she makes. But she does have feelings for him and fears rejection.
