If I remember correctly I think there was a some plot rumor that the Glee Club discovers something about Sam’s home life and it had to relate to his siblings. I’ve been thinking about it since the recent promo for “Rumors” aired and here is what I can come up with.
Sam’s home life isn’t great; maybe his parents argue a lot, or one of them is a nasty drunk. When things get bad Sam takes his younger siblings to the motel and stays there with them until things cool down back home.
The reason we see Kurt and Quinn there is because they know Sam’s secret. Quinn knows because she used to date Sam so she probably met his siblings or at least knows of them. Kurt knows because he and Sam have a unique friendship. We’ve seen Sam be oddly protective and accepting of Kurt and I feel like Sam would trust Kurt with this secret.
This is just what I think, I don’t know anything for sure. I’m just sharing my theory…let’s see how far off I am next week.
wow… that makes total sense! I forgot about that spoiler/rumor about Sam’s family
