Yeah, I think they could be or at least derived from Double's flesh, but look at the designs. Elongated bodies with ridges running along them. Circular mouths lined with row of teeth. Extendable long tongues. I don't think any of Double's transformations we have seen have these design languages.

It's not that I have a problem with Dahlia and the Skull Heart having a back-and-forth conversation, it's the way that the Skull Heart responds to her. Like I said, the Heart is able to read her mind, so it must already have an idea of what Dahlia is thinking most of the time. If the Heart's dialogue had been written to communicate this better and using less words, I think it would have made it more menacing and seemingly omniscient, which would be more fitting of the eldritch wish-granting device. The way the Heart talked just seemed like it was one step behind Dahlia all the time and sucked all the sinister aura out of it.
Err, I think in Double's ending it was implied pretty heavily that the Mother is there with them given that she called them to go to dinner. I think what we actually see is Aeon's room and Venus just comes and hang out with her sometimes. The Abyss seems to be a pocket dimension but I'm pretty sure there are other areas apart from this.
Lol, would have been nice although if they have time to redo the original stories, I'd rather they spend it making Nightmare Legacy. :P
I think it probably takes some time to work, especially if the user just got hold of it. For example, Fortune was cut up and thrown into the river, so she must have appeared dead at the time. Probably took a bit of time for the Life Gem to take effect and animated Fortune, so maybe it can reverse their aging back to the user's peak physical age if given enough time.
Or maybe not and it just freezes the user at their current appearance. In that case Lorenzo must have got it as a young man and never parted with it for any significant period of time until now.
Yeah, that's definitely part of my issues with the joke stories like Robo's. I honestly don't think it was supposed to be taken seriously and many other characters we already saw previously were acting way out of characters. Based on what we know about Aeon now, she was probably acting out of character there as well.
