Ok, actually… you’re kinda right. I mean, they just keep punching each other and we’re calling it “being in love”.
And they can’t absolutely stand each other…
Also when they were in the hospital in 6x09 and Theo said:
You’re going first.
That’s the only reason I’m with you.
Because while they’re busy wrapping a whip around your neck, or shooting a hole in your head, I’ll be running the other direction.
I’m on your side as long it helps me.
And then Liam said:
I also think whatever happened to you, you deserved it.
When the Ghost Riders find us, I’m not gonna do anything for you.
I’m not gonna help you.
I’m not gonna save you.
I’m gonna do exactly what you would do to me.
I’m gonna use you as bait.
Oh, hang on a second.
Didn’t they save each other from a ghost rider right after that?
And isn’t this Liam saving Theo?
And isn’t this Theo saving Liam
in the exact same way?
Also, is that Theo worrying about Liam?
HE PUT A HAND ON HIS SHOULDER AFTER THIS
Theo: I went trough all of this to keep you from being taken.
Plus, in 6x15…
Theo: Those two losers killed hunters.
Liam: Who killed their pack.
Theo: So what? I mean, Monroe’s gonna tear through anything standing between her and them. That means you, Lydia, Malia and Scott.
Oh, and here’s Theo looking at Liam with heart eyes!!
HE WAS IMPRESSED BY LIAM
Theo not only saved Nolan, but he stopped Liam from doing something he would’ve regretted.
Liam can’t stand Theo but
Theo: You made the plan.
You wanted me to help.
Liam: If I needed your help for anything, it’ll be so I get angry enough to kill you myself.
Theo: You brought me here because that thing that came out of the Wild Hunt is affecting you, too.
Not Scott, his alpha. Not Mason, his best friend. He choose Theo.
What’s more, they’re such an amazing duo.
We’ll see them kicking Gabe’s ass as well
In season 5 Theo actually said:
I love this kid.
And let’s not forget who made all this possible by bringing Theo back…
In conclusion, yeah, you’re right, they make no sense.
But I’m not sure we’re watching the same tv show.
