6410: Andrew discovers Griffin is a cheat

Seeing Summer invest in her new romance with Griffin, Andrew works to secure his business with the band despite his tension with his ex. While he is buoyed when Griffin co-operates, Andrew is hit for six when he catches him with another girl. Unable to stop himself, Andrew confronts Griffin and is confused when Griffin insists he and Summer aren't exclusive.

However, when Andrew learns that Summer thinks they're serious, he tells Griffin to stop hurting Summer or he'll dump Red Cotton. Griffin calls his bluff and Andrew ditches the band from his list. He warns Griffin to stay away from Summer, but Griffin has other plans. Oblivious to the truth, Summer continues committing to Griffin - only for Andrew to see they're still together.

Meanwhile, Sheila tries to cheer up Kate after her cancelled date with Kyle, but Kate panics when Sheila wants to look at the books. Kate fears she'll lose her only ally if Sheila discovers her cover-up of Lou's underhandedness. While she manages to keep Sheila off the scent, Kate realises they need to pay the money back immediately, and takes care of the debt. Lou is furious, but Kate insists he can still salvage his pride - by owing her instead.

Elsewhere, Karl throws himself into preparations for The Right Prescription's next gig. However, when his creative differences with Ajay continue, Adrian reaches boiling point and quits the band.
