T-Rex: The Americas! They're initially colonized by people NOT named "America" who walked over from Asia -

T-Rex: - then rediscovered by the Vikings, who were, again, NOT named "America" -

T-Rex: - and then rediscovered AGAIN by an Italian who, I hasten to add, was ALSO not named "America". Columbus MAYBE named them after a mountain range the Mayans called "Amerrique", or MAYBE they're named after an English merchant Richard Amerike, or MAYBE they're named after explorer Amerigo Vespucci, or MAYBE they're named after something else?
T-Rex: Because NOBODY KNOWS FOR SURE??

Utahraptor: And if they WERE named after Vespucci, he died without ever hearing about it. Hilarious.
T-Rex: Whoops!

T-Rex: My point is that if we have two continents named after something random, like SOME GUY who WASN'T EVEN THERE, then it stands to reason that it could have easily been some OTHER guy, therefore, everyone is SUPER JUSTIFIED in renaming "America" in their alternate history stories.

Off panel: ...That's why we're talking about this? That's a ton of real-life justification for a pretty minor artistic choice.
T-Rex: Oh, I don't research ANYTHING unless I'm looking to prove a petty point. And ladies love me!
T-Rex: For SOME reason
