Third, the "I am your brother" speech is an obvious rip-off of/reference to The Empire Strikes Back. It was most likely said for comedic value, not a plot device. It would be lame for the nature of Guybrush's eternal battle against LeChuck to hinge on a tired Star Wars reference, which is why the newer games don't pay attention to it.
It was just a theory of mine. Ron has since confirmed that it was meant to be a major story arc for the third game. The newer games do not pay attention to it because they were not made with Ron Gilbert's input, who had a different idea for the third game. I also don't think that logic plays that much of a role in Monkey Island. Guybrush said they were his parents and I wouldn't understand why Ron would have his characters say lines like that unless he is hinting at something going on in that scene.
