Karin Smart (Denise Van-Outen), immidiatley tricks Max Branning following her arrival in Albert Square. The only reason she is there is Phil Mitchell! She's indeed smart. (Get what we did there?)
She's a dodgy dealer with her eyes on the prize, and no, that prize isn't Max Branning (Jake Wood), it's Phil Mitchell!
Phil calls in Karin to fool Max, in bid for him to sign the Arches, back over to him. But Karin is actually dazzled by Max, and takes him to her bedroom, but not for what Max thinks!
Karin is shockingly flirtatious towards Max, and when Max kisses her, she leaves, sticking to her loyalties. She pays a visit to Phil, what's next.
