Check on.

He indeed went to meet that person at midnight... after that, he basically disappeared for two whole days, without leaving track nor giving any news to anyone about where he was or what he was doing.
During the night of the second day, he finally returns to TOP's home. It's pretty late night, he waited on purpose that long before entering inside, hoping that there would be nobody still awake, least of all TOP himself.

He jumps over the gate and teleports right in front of the door inside, since he doesn't have the keys of that place and doesn't want to drag attention by ringing the bell or burglaring the lock.
Once in, he slowly limps towards the closest bathroom, leaving a trail of blood behind. Not much he could do about that, he is pretty much entirely covered in blood, most of which his own.

Reached the bathroom, he doesn't even close the door and just falls on his knees, taking off the ripped clothes still 'stiched' to his body. There, he starts to pull out the bullets from his body, with bare hands, as he has always done.
He gets it done pretty fast, regardless of the terrible pain.
Clinging to the sink, he stands up and pushes himself to walk towards the shower, but falls and simply crawls inside of it, where he opens the cold water and remains under it, not even taking off all of the clothes, just the top.
