Lin (Undertale AU)

You arrive at the last corridor..Everyone and everything being dead because of you...But..You pause to see Lin..? You had no idea what he could be doing but he did had one thing to do to..Avenge his friends.. "Heya, my friend..You don't look well..." "Why don't you take a break..? And the play CSGO together.." Na...h...h...h..." "If they're still here..It should be very lively now....." He thought "You should be able to hear the pain in the depths of your soul....." Everything changes now..Lin's behavior now changes causing the color of the corridor to change to red..He then manipulates a red crystal from the ground to impale right through your body but to your surprise it doesn't kill you...But just hurts..The crystal also didn't seem strong enough to keep hold of you for long.. "So now tell me..Why did you kill all of them hmm..?" Lin asked clearly trying to get an awnser out of you.. "Was it all for fun..?" "....."
