[@AHeartlessNobody] Hmm, That's a toughie. I don't think I can decide it on my own. 

The Star Wars fan in me says, let them duke it out unknowingly. But that's a bit cliché. What if they both knew and instead, still fought. Some circumstance making them clash, even though its tearing them apart. Whatever it may be, it'd have to be something important enough to have the both of them seriously trying to kill each other. 

Tell me thought, which of the choices do you prefer?
