We have uh, a bit of an alternative family. Maryanne and I were together, and Tony and AJ were together and somehow we all ended up forming a weird little family with each other. When I first started seeing Maryanne she had a son from another man, Timmy. Later on we took in another little boy a 5 year old, now 6, named Buck. Tony and AJ have had a son, Richie and Maryanne and I have just had 3 of our own.
I consider all of them my kids, but I want them to know where they come from too. Bucky already knows we're not his biological parents, he was in an orphanage before he came here, Timmy will know because his older self is here and I'd never want to try and replace his father or Maryanne's first husband. And while I do think we all thing of the children we've had since getting together as as much our own as the others, I still think it's important for them to know their biology.
