Okay I'm wondering something.
If the scientists in GWH are still interested in studying Coco, why did they leave her someplace where she can get adopted and they might not be able to get her back?
I suppose their "main" work might be done and they just used the 5-year picnic as an excuse to slip in some extra studying, but I dunno. It seems like they find her highly fascinating, so it just seems like they ought to have just kept her. *shrug* (And yes I know, if they had kept her, she wouldn't have been in the show, etc.
Lol.)
