im pretty sure the brother in law is doing all of this just so the brother and the sister wont talk to eachother anymore, since all of their fights were about her after all.
And tbh the sister is pretty fucked up imo,
you see your husband doing THAT to your unconscious brother, and you blame him(the brother)??
Not to mention, he outright told you (the BIL) that he was inlove with your brother, how delusional can a person be to think that its okay to marry a person like that
And btw as a SISTER, how can you date/marry someone who your brother has dated and loved? Thats just so nasty
Anyways, i really am curious to know what will happen. Im pretty sure the brother in law is the villain in this story.
