Lionel is actually really cool headed. You have to go out of your way to piss him off, but he is fittingly very cold and steely if you do. A cold flame that burns slowly.

Estella is extremely vocal and will absolutely let you know when she is peeved. She'll march right up to you and let you have it.

Heather is far more bitchy. She'll throw shade and snipe at you. Unless you're close to her she won't come to you to talk it out, you'll have to go to her.

Lex also gets sort of cold but he is far more brutish about his anger than Lionel. If you REALLY manage to push him then he'll basically explode on you.

Shayla might actually just box you out, then apologize but explain to you why you deserved it. It takes a lot to get her there tho, like Lionel.
