Megan is a sly manipulative bitch who wouldn't bat an eyelid at breaking a couple up...she smiled at Laura's reaction and loved every minute of it...I bet she's like that on the outside world too. She happily snogged Wes but didn't like Eyal snogging Ellie
Having said that..this series needs her and she hopefully will get her comeuppance. Also Laura is very needy...and her and Wes were never going to happen..
Megan and Adam are very alike...they like their ego massaged and will walk over anyone to get what they want...Adam is biding his time with Zara..she's lovely but a bit dull.
