Maybe Daisy should come back and maybe Luigi will turn back to normal. I have a feeling that the guy in the clocke gave him a corrupted fire flower. It probably put a spell on Luigi and turned him into Mr. L. Cause Luigi seemed fine before he showed up.
He definitely was not fine before getting the Fire flower, he was still vengeful before he got it. (I don’t give a rats ass if I’m commenting 11 months late.)
I don't know why there mean to luigi I mean yeah sure he's a criminal but it is there fault for never visiting luigi and leaving him alone for all those years.
It’s not their fault he’s a criminal. Luigi was avoiding paying taxes for years, he deserved to be in prison and he CHOSE to blame it on them. Luigi tried to kill his own son and brother, they shouldn’t forgive him.
