They're not actually copies, the teen version is the actual teen Warren from way back when brought to the future years ago, the teen Warren dated Laura, the grown Warren seems more intent on sticking as close to Betsy as he can, over in Blue there's a character called Bloodstorm, but not the one from the Mutant X universe where she first showed up...it gets confusing quickly...and don't get me started on Jimmy and the others...
I like the reference with Remy and the dragons, considering that his first (and last encounter) with one was in the X-23 solo run.
