A really short explanation to how Alexis got her nickname from Dean.
Nicknames
I've been called a lot of things by my older brothers. Sammy used to call me Lecki, since he couldn't say the x. It was a family joke for a long time. It became irrelevant by the time I was seven, (although he still slips up), when they started coming up with new ones like Squirt, Loser, and Twerp. No matter what though, the one name that stuck was Ankle Biter.
Dean has called me that for as long as I could remember.
I can't exactly remember the real reason; although I am pretty sure I never bit anyone's ankle. I asked him once, not too long ago, and he claimed that it was just something he decided one day. He jokes that I was "a biter" as a kid. He used to have to give me things to chew on when I was teething. Most of the time it was his fingers that I chewed on, since we didn't have anything in the motel rooms. I think the real reason, that my dad said once, was that I was so short compared to him that I was "able to bite his ankles." Dean calls me it all the time, whether I want him to or not, and it stuck, I guess, even though I am taller now and (unless he really peeved me off) don't bite him.
I don't mind.
