The Tail Section

Here is the actress playing the semi-recurring flashback (?) character of "Charlotte".  Indications are she will figure heavily into an interconnected flashback "epic" that begins in 2.21.  For spoilerish info click the link below the pic.

Her name is "Brooke ‘Mikey’ Anderson".  For more info on the actress visit IMDB.

Spoilerish stuff.  Charlotte is an Australian character who has a near death experience.  She also purportedly involved in the finale.
