It's Deker
And 3-4 other girls.. Indeed i believe that was the problem with Serena "scandal" on last visit, because he was with another female.
Emily will have the guys kira wants and only do what kira allows, remember the last time of drama because emily make out with an extra dude and there was no problem that just moments before she had make out with Deker
And last night, after all coming from malena&amelia, Deker was pissed at least with Emily (don't know if kira also) and was refusing emily trying to talk with him
