There's probably some kind of analysis to be had in the fact that almost every supernatural OC in tamers has three or more direct contributors to their birth. Flawless is a Twilight/Trixie hybrid, but couldn't exist without Rarity's spell, Twilight played a surprisingly important role in both Arinos and Friendship's emergence, and Sombra was the catalyst for Parcel Core. There's a running theme of parents who are making no attempt to have a child, but due to the interference of a third party, one results anyway. To be honest I really don't know what that implies, but I find it really interesting. In every case, the third party has zero emotional investment in the original relationship, which makes me wonder if it's a commentary on the social pressure to have/raise children. That would line up with Soarin's TED talk where he openly states that he has no intention of adopting a kid, but ends up taking on something of a fatherly role towards Friendship in the end. It's not always positive, either, because Parcel Core is openly rejected by his parents in the end. Care Package says they don't really know who Parcel Core is, yet, and part with him and Arinos reads a lot like an abortion, especially with Care and Split quipping about being unable to afford a child. Combined with Care Package's line about Parcel Core lacking time spent with them as a family, it sounds more like that they weren't ready yet, rather than an outright rejection of the possibility of raising a kid. Having him get adopted by Care's dad is interesting as well, although combining abortion and adoption muddles my analysis of it a lot. It seems a lot more straightforward with Flawless, who plays the part of a troubled child much more obviously, and the unconditional love she gets from her parents is very sweet and makes her entire arc feel a like what someone wishes they could have had during a troubling time in their life. I'm reminded a lot of this greentext when I see scenes like the movie rental at the end of Tournament of Power.
The other ones are played more cynically, and focus more on how it affects the parents, which is an interesting contrast.
