Re: Carol Marcus' British accent
I just assumed that in the Abramsverse she spent more time around her British mother growing up and in the Prime Universe her father had more of a presence in her life. Hell without the looming threat of a Romulan space octopus that could destroy planets, maybe Alex Marcus Prime wasn't as career driven and eventually retired from Starfleet to focus on a family life?
