Kai wasn't noticed by forest, he didn't bother he was eventually in his room and then he disappeared again, he had to find somone he could.. trust
Blindly travelling through the hall way.. faster than usually while flickering.. to describe it it's like flying without a body.. Kai had a million thoughts in his head..
He learn't that you can't go through solid objects, you'd have to go around or spread in different directions, but all Kai was doing was spreading his body enough to not be seen, and he could also travel through the air faster.
He was getting dreary.. and didn't know where he was, but when he realised he wasn't flying through the air, back to normal running towards Nyx and another Guy... he just struggled.. he had tears running through his eyes.. the guy who was chasing him was still there.. he felt it.. he couldn't make out real words.. just breaths of gibberish
crashing into the wall near Nyx, trying to spit it out.. "Thwahh, frabb--ehh--baahhh.. I..B..Behh.... arhh... Er" he said his knees keeping him up on the ground.
He looked behind him and saw what now looked like a black shadow chasing him.. and flickered again.. he lost it.. and aimlessly flickered flying into what now looked like forest, who was standing next to a guy with a creepy smile on him.
