More Confusing Than an Episode of Lost

Today my dad came over to pick up my dog after we dogsitted her three weeks. When he dropped her off, he answered soooooooooooooo many questions with answers that led to more questions like "why was he going to the airport" and "why did he say that in a few years this will all be over" and "why the eff does he care about me now?!?!" Well, today he answered and then just told me straight to my face that I have a half-brother I not allowed to meet,but hey his name is Tobey.WTH just happened?!?!?! I really don't know how to react,or what to say,or what to do. All I know is that I'm confused and I'm sitting here with a blank look on my face.
