Thanks for the comments, guys! ^_^
Also, random answer: "Since one of the OG Ice Age vignettes implied Kal was the one who introduced Lois' tribe to the concept of language, does that mean the cavepeople are actually speaking Kryptonian (or at least a simplified version of it)?"
That actually wasn't what I was aiming for. Lolo's people, being more advanced than Kal's, already had a language of their own. It was his first time meeting people capable of speech and all the complexities of thought that could unlock, and yes, his powers did allow him to grasp their language quickly.
