Who in the hell is Penny's mom? I feel like they are subtly building her up to be a bombshell for all of us.
Any theories? Is it Claire's mom? Charlie's mom?
Any crazy theories? It's Libby who traveled back in time to the Adam and Eve timeline before the original jughead exploded in timeline 2 and then grew old and moved off the island when the island sank due to Walt's volcano eruption in timeline 9 on the sub to michigan and got a job at sawyer's shrimp truck and met widmore at a lamp post convention in tampa where she posed as an economist named annie.
