I was re-playing the mission and when i failed to save Franklin after saving Jimmy,Michael parked at the side of the road and this is the dialogue (Not exact,I don't remember it very good):
Jimmy:(He said something like)Don't be a total Butt Hurt (Or something like that)
Michael:Listen you little sh*t,that kid jumped of that hood to save you and now he's gone along with my boat.
And then it said "Mission Failed"Michael didn't save everyone or everyone on time.
I will replay it again and see if i can get a picture.
