Ok so from what i can gather the second hokage died that day when he was out on a mission with his team (the ones in danzos flashback) so thats when The 3rd became Hokage. BUT what im a little confused about is that the 3rd had his own team (Oro, Jirya and slug girl) and was allot older in the flashbacks where he is shown with them, so did he train those three while he was hokage? or did the 2nd live a little longer. it just seems like the hokage would not have time to train a team like a regular teacher.
