Tamsin reels from the events of the night before while trying to get the unsettling news through to co-worker Alex. 

Struggling to come to terms with who might be watching her, Tamsin and Alex work out how best to deal with the voyeur.

Attempting to appear as unperturbed as possible, Tamsin shows up at work and is interviewed by the police, which sends Alex spiralling.

Tamsin advances her side hustle while her sister back in the UK continues to worry about her fitting in to her new life.

Armed with her own, new information about what was in the dropper bottle, Tamsin is once again questioned by the police in the office.

Alex and Lee's messy break up, Tamsin's entry into Singaporean life and work, and the error that started it all.... 

Tamsin and Alex, increasingly desperate, put their plan into action.

While in the present day, the investigation into his disappearance continues apace, back on the night in question, Lee gets the measure of Tamsin.
