Alex X Luke - Tumblr Posts
I just thought of something...
The boys are originally obsessed with confronting Bobby, right?
Well, why didn't they just get Julie to play a song with them in front of Bobby? They could write a song about their feelings of betrayal toward him? The way they did with Flynn. Reggie even managed to talk to Flynn in the Flying Solo performance so wouldn't that have made sense?

I'm thinking too much these days, but if you listen to the lyrics of "You got nothing to lose", there's a line like "Listen to the words a wise man said; he said "Covington, I got an offer that you can't refuse""
This could be a reference to when Caleb first became a ghost and how he got into the whole ghost club scene. How he got the same offer that he's giving the boys from another ghost.
As a firm believer that no one is born evil (some exceptions absolutely do occur), I think there's a lot more to Caleb's character than let's on.
I have two theories as of now.
1. He could be out for revenge.
This could be his “modified” unfinished business. He could have gotten into the deal himself centuries ago and he’s been looking for someone to pass the deal onto so that he himself can pass on. It might seem selfish but really it’s only human. Self-preservation is the only way to survive, right? Not that Caleb has that problem anymore but you get the point. So really, I don’t think he’s evil in the way he’s perceived.
2. He genuinely thinks what he’s doing is right.
This theory comes from the “no one is born evil” belief. If you think about it, what he’s doing could absolutely, in the right context not seem as terrible. He’s offering the boys a secure way to keep doing music together forever, and be seen by actual people. His motivation methods are extremely wrong but you know, we don’t know how long he’s been dead and his perception of society might be so incredibly ancient that the only way of negotiation he knows of is through violence. But like I said, I don’t think he’s necessarily a bad or evil person.
So, in conclusion, I don’t think Caleb is the villain we’re all seeing him as. He’s desparate. He’s lonely. He’s probably bored out of his witts to be honest. Imagine playing the same song over and over again. As a musician myself, and performer to some extent (eh, mostly school related concerts), I can absolutely see the joy in performing like that. Hell, I would do anything to get to perform like that. But for all eternity? Come on!
Personally, I think Caleb is just a bit old school and he needs someone to guide him through the improved ways of the world
Thank you for coming to my TED talk. I hope you have a wonderful day and happy holidays!

Luke is still pissed at Alex's parents. Even after Alex has moved on, Luke's still so mad at them for the way they treated Alex. The way he expressed himself in episode 2 when they were at the beach. The desperation he feels for Alex and how his whole expression shows it with that one line is incredible to me. I mean, it also proves how freaking talented Charlie is as an actor but that’s a different point.
