Lou's recent murderous hyperbole about the Shield is merely Lou doing battle with his mental and emotional peer. Lou is letting his resentment of the child ooze out into his digital life. The Shield is Mama Gags do-over child, and Lou resents the time, money and attention that everyone gives to the child.
I imagine the scene looks something like this:
The Shield is now about 10 years old. It is the age for kids to start noticing the world around them, and no doubt, The Shield is aware of how...weird...his gargantuan, skirt-wearing Uncle is. Add to that; it seems his father, Lou"s half-brother, is a Trump voter and is now residing in the Gagliardi compound. It must be quite a strained and strange atmosphere. The Shield may even have called his uncle a name or 2...at the least, he probably avoids Lou like the plague. That's good. Stay safe, little dood.
All that to say: I hope that this latest nasty talk of slitting his nephews throat is only a twisted form of sibling-type rivalry and that Lou is at heart, a cowardly, powerless, unaccomplished blowhard, who wouldn't dare lift a hand to anyone, much less look them in the eye and say the shite to them that he says online.
I am Thankful that I was not born into this family.
Frens, I hope you all have something that you are thankful for also.
