As much as I love the O'Reilys (especially Fiona), there's no way they would deserve a spot over Tanya. Hell I'm pretty sure the only reason Tanya isn't part of it is because for the purpose of the plot she was already pregnant, and well some people get weird about pregnancy on here for
whatever reason. (though maybe that's not the only reason)
I actually thought about something a while ago... aren't the M7 gonna be pregnant no matter what anyways in the future? If so there would be unavoidable pregnancies regardless so I'm not sure why Tanya couldn't be a "main" LI (I mean she basically is, just optional unlike the others) in that case. I mean obviously too little too late anyways, but still I feel like Tanya fell on the sword for kinda no reason tbh.
Anyways, I'm just blabbing at this point, hope everyone is doing well imma get back to my game.
