okay here it goes Miles is Louie from the hauted hathaways
before you say that's crazy talk let's back up for a second
in the episode quadbusters there was a ghost at the end of the episode
and even though He is dead I think they can still age for some reason
plus maybe just maybe between haunted family and keeping up with the quadashians the other Miles and Louie moved to different and maybe Louie moved to a different city after his brother did (another city) and so Louie moved to where everyone has the gift and skin like gloves and such so people can feel him (like the other Miles sockpuppets plus he wanted to remember his brother so he's decided to have his human name been Miles (there is a second way though) maybe Louie transformed into what he looked like in about 2-3 years and maybe he became a level 3 ghost sometime between haunted family and keeping up with the quadashians and transformed into somebody who does age (if they don't age) (note there is a third but it's almost the second way with a slight touch of the the first version they do age and they just transformed into what they would) plus we don't see Mirabelle parents which makes me think ghosts don't need parents
Anyway that is my theory i'm not think it's true but I don't really make theories. (plz tell me what you think)
starforce there is person called BLOCKMEANDYOUWILLEATSMEGA (sorry about caps but that is his username) who is making mean swearing comments (in fact now that I think about his username and deju fu (I think he is that sextingisfun guy)
For the theory, I like it... but... I don't believe the one at the end qualifies as an actual ghost because.
1. I'm pretty sure if the story continued, it would turn out to be just someone else messing with them and not an actual ghost. That was basically the theme of the episode... some characters think there's a ghost... it turns out to be someone else... and that someone else ends up being pranked by someone else etc.
2. NRDD is not a supernatural/fantasy show. So, things like ghosts, zombies, superpowers can't be canon.
3. In NRDD universe, The Thundermans is a show which means the Haunted Hathaways is a show too because Thundermans and Haunted Hathaways are in the same universe. So, their characters can't show up on NRDD unless it's like a dream like Dawn's dream in The Wonderful Wizard of Quads where they had Dr. Colosso.
Some shows might not care about mixing supernatural elements or characters from other universes into their show... but NRDD writers seemed to be very careful about the rules.
If we forget about the rules for a second, I would actually say Miles is the same Miles from Haunted Hathaways. He had the ability to change his appearance and look like someone else. So, maybe, he still kept his Miles name but changed his appearance.
Yes, shows do crossovers. But since Thundermans did a crossover with Haunted Hathaways which puts them in the same universe... but since we know NRDD and Thundermans are in different universes, it means we can't mix them.
Like the quads can't say Louie is a character on a TV show but at the same time interact with him in their world. I hope that makes sense.
