Danny took her from the premises. This caused a panic and the folks at the camp--called her father because she was missing. Danny is 16 and should know better. His judgment is horrendous.
He could have:
1. Called Drew and asked permission to take her to the park or the MC pool to see Rocco.
2. Asked Drew if he could pick her up when she was done with camp.
Drew being a douche doesn't negate Danny's stupid behavior for me, because Drew is her father and has final say on his daughter's comings/goings. Jason was wrong for not calling Drew immediately as he stated. He called Alexis first. Alexis looks bad here for not alerting Drew immediately when she saw Scout at the Q mansion. I get why Drew is pissed at all three for the reasons above.
