Chloe goes missing.
On assignment for Nicole Farhi, Lydia meets Becci, another freelance fashion writer. The two have had similar experiences, and although the pair get along, there is a hint of rivalry between them. Lydia is soon called in to help out with ELLE's 25th birthday party. Although the event is glamorous, Lydia's role is to do general drudge work, and she soon discovers that Becci is also hired to do a similar job. Lydia's fortunes appear to be changing when she is asked to assist a videographer who will be covering party arrivals for ELLE Online. However, Becci also tags along with the ELLE videographer. The two girls get talking about Lydia's new flame Charlie, and Becci encourages her to leave the event to go and meet him. Against her better judgement, Lydia goes to see the boy she cannot stop thinking about. Is Becci doing Lydia a favour, or trying to steal her thunder? Meanwhile, Chloe's behaviour after her meltdown on the roof (see last week's episode) grows increasingly erratic. Lydia, missing the warning signs, repeatedly snubs her cousin in favour of working. Eventually Chloe snaps, packing her bags and disappearing into the night. Will this spell the end of Lydia and Chloe's friendship? Elsewhere, Alex reconnects with an old flame, and Tom finally breaks off his engagement to Rachel. Rachel takes the news very badly and confronts Lydia about her and Tom's dalliance. Will this confrontation lead to a lasting bitterness in the friendship group?
