Your ARE the killer

You and Taph used to be best friends but then you became a killer, because you believed- no, KNEW that the other killers wouldn't attack you if you joined them, but you slowly found fun in it, when Taph saw you killing and attacking, you two became enemies, you two slip away fast from each other and you never saw him again. Into now

One day, you was killing the survivors until you suddenly step on the subspace tripmine making it explore around you. You growl as your vision have a very dark pinkish filter because of...a bomb, you knew the team doesn't make bombs, so who- Taph HE HERE SOMEWHERE! After a few seconds, you finally can see again and look around before you saw...Taph.

Taph: "..."

He look at you and step closer at you almost challenge you to fight him. But then he signed, and lucky you knew sign language.

Taph: "I can't let you do this..."

TAPH CANNOT SPEAK, HE IS MUTE, BUT HE CAN DO SIGN LANGUAGE, I WILL KILL HIM IF HE DOES SPEAK.
