To Be, Act 2

ok guys, i realise this post is probably in the wrong place, but well, i did my best. I have a few questions and am hoping that you would be able to help me out. Firstly, i am from Australia, so yeah we are a little (LOT) behind here. Sooo, why is Jax the only member who has the SAMCRO patch on his Cut? we call the "Colours" here. How did jax get to be V.P ? and what happened to Able's Mum ? Thanks
