Everntually steve accepts that this wont change. He says "Bye i'm steve" showing that he's lost who he truly is,
given that this line is almost exactly the same as the first line of the video, it seems hard to argue that we're "lost." seems more charactaristic of something being "found."
...A couple of nice bonuses i found in the last line, 1. it sounds exactly like the first line (hi/bye rhymes) 2. you don't normally introduce yourself when you leave, which makes for an interesting sounding phrase that you don't hear too often, and 3. adding further controversy to the name issue, as if he just admitted his name was steve? either way it's nice closure because he said that at the beginning as well.
