How come nobody is talking about the fact they may have just revealed Luke is gay? In the second episode this season when his dad is walking him into school he responds to something he says by saying what am I supposed to do go up and hug that big guy there? At the end they show him hanging out with the guy and he makes a comment about his smile. On top of that, Phil's voice over mentions seeing a lot of things that didn't make sense then but made perfect sense now. Maybe it was all a red herring but if it was too obvious to be real, I'm surprised nobody seemed to notice.
