I'll grant you that the meeting Fry arranges at the end of BBS is a noble and thus mature thing to do, but don't you get the feeling throughout BBS that this is just not the same guy from TDHAIP? Especially if you consider the cut balcony scene he seems to be suffering from amnesia, at least where that episode is concerned. I think it's due to the notion that TDHAIP was a finale that the producers want to effectively undo (by pretending it didn't happen) and then re-do when the true finale comes, be that Green Yonder or (hopefully) some even more future Futurama.
