As their debt problems mount, Fiz is furious with Tyrone over the Lapland trip that just won't quite, while Dev worries for Mary's safety after she goes for a ghost walk with a strange man (from The Inexplicable, no doubt) without her phone. Meanwhile, Tony tries to win Liz's heart with tickets for a Rod Stewart tribute act, and Nessa gets on Audrey's nerves during her first day at the salon. Yep, she gave her love rival a job.
