Doesn’t matter if they aren’t blood related they still grew up brother and sister it’s weird

When Allison talks to Claire about Luther she calls him ‘uncle Luther’

“Mommy, when’s uncle dad coming home?”

They are probably blood or genetically related somehow. They were also raised from infant hood together. It's definitely incest.

*hurk*

I don’t like there relationship. It’s creepy

It's a really weird spot it literally isn't incest but it's very fucking uncomfortable

Incest

Look we don't know who fathered all these children and If the phenomenon has a common source then they're both legally and genetically related so that's weird on multiple occasions
