The situation is a bit Lionel messy. If you and your brother agree with each other more, you are in a situation where the others think you are cliquey.
If you and your brother were more like Liam and Noel Gallagher., then you would've been in a different band now anyway.
Unfortunately, I forsee a little tension at your next gig , the other members and yoko (if she can take her head out of her a&se) will probably notice it.
You will subconsciously be a little on edge, and it will probably be the gig that will decide if it's for you anymore.
Sorry for sounding negative, but that's how it looks imho. Hope things work in your favour. Don't forget, there is a thread on here about loss of hearing/tinitus .
You want to avoid that, and so should they . On the plus side, it'll soon be Xmas
