Who made the biggest relationship blunder?

• Adrianna, by dumping Navid

• Teddy -- first for saying he "didn't do relationships" to Ades, then for telling Navid about the kisses

• Harry, by saying Kelly's name to Debbie

• Annie -- first for letting Mark convince her to go with him, then for not realizing that Jasper is a potential psycho

• Dixon, for continuing to fool around with Sasha
