Sorry for taking so long to answer, I'm not an expert with this forum, so I don't know how to share pictures haha! The script, it's on the second page, you should be able to see some dev comments in french and the dialogue written in Pig Latin (if you scroll to the left you can read the translations, however they cut off most of the time)Could you pinpoint where in the script those lines from Murfy are? They seem pretty clear, but I've never actually looked at that document before, and it's torture to search!
This indicates that the developers' intention was for the heroes not to realize that they're dealing with a Teensie as long as he hat his hat on, and therefore that, in the final game, the end of level sequences should not be interpreted as revealing anything of the sort to the heroes. That's dumb as fuck, because once again, it's obvious to the player that it's a Teensie, but then again, Rayman Origins so poorly written that it shouldn't come as a surprise. At least, at some point during the game's development, the writers were happy with this kind of storytelling.
When i played Origins with my brother i didnt even notice Ales, My brother just thought his hat was cool.
