What if Branch Killed Bash...?

Warning this Story will involve the Death of a Character and Angst, not to mention it will probably be Dark.

My Friend @powxbash aka Tinatina had an idea that What if Branch actually blasted Bash with the Trolljitsu energy blast and it ended up killing him by accident. So it gave me an idea for an Angst Story in an Alternate Universe this does happen and it upsets Archer that Branch accidentally killed his brother. even if Bash is terrible to Archer I don't think Archer wants him dead. This causes Archer to not be friends with the Trolls once again and Archer ends up on the Party Crasher side again out of the anger of the death of his brother. Archer now seeks revenge on Branch for killing his Brother and the Trolls and Party Crashers are in a Conflict. I kind of feel bad for writing this, because man is this going to hurt my heart, I don't like when my favorite characters are against each other and hurting but this is like the perfect Angst fic. I wonder if this would be considered Whump, personally I never really like Whump but this does sound kind of Whump, which I don't think I exactly understand the definition of Whump though.
