Narrative:

Our passenger boarded the flight at the very end of boarding. I noticed him walk on with the gate agent who was asking him to put his mask back on. The gate agent then told me that they had been trying to get him on a flight for 3 days. I asked more about this; feeling a little concerned as to what could have caused them to deny him boarding these previous days and if it could be an issue during the flight. They told me the previous days he had not wanted to board the plane. He had explained to them that he hadn't gotten sleep and also hadn't eaten. I'm not sure what happened those past few days but it was communicated that he had gotten enough sleep and was able to finally board the plane.I made sure to ask clearly if they thought there might be any issue during the flight or if there was anything I should know that could cause an issue in-flight. The agent I talked to said she thought he was harmless.during boarding a woman nearby asked if he was going to wear his mask. I looked over and he had it down at his chin. I asked him to put it on and he did. This was an ongoing issue during the flight - he kept taking it off and we had to keep asking/reminding him to put it on.while taxiing to takeoff he got up out of his seat and moved a few rows back. I alerted the captain but by this time he was already seated back down. We took off. I had him move back to sit in his original seat and he seemed fine the rest of the flight. Right before takeoff while we were still taxiing; [he] got up out of his seat and moved back a few rows to the exit row. I called the captain and let him know someone was out of his seat. By this time [he] was seated a few rows back. The pilot made an announcement that everyone needed to be in their seat and then we took off. We just continued with taking off when we were scheduled. The thing is; [he] was now seated in an exit row for takeoff and he had not been briefed to sit there. I also doubted his ability to perform the necessary exit row duties. Once we were up in the air I did go back and confirmed that [he] was now seated in an exit row. I had him move back to his original row where he stayed for the duration of the flight. The only other issues we had was that when I would walk by he wasn't always wearing his mask. I would remind him and he would put it on. He seemed not to be intentionally doing it but perhaps just not mentally 'all there.'more communication from csa to csa. When we arrived in ZZZ1 I alerted the gate agent that we had a meet and assist and the D flight attendant pointed him out to the gate agent as he deplaned. I don't think the extent of the situation had been communicated. Then again it's not our job to babysit people. Maybe his family should have been contacted and asked to fly with him? He seemed unfit to fly on his own.
