Lena seems to be Mimi's opposite in most ways (Other than appearance, that is). While her sister is more level-headed and pacifistic, Lena herself is much more crazy and ready to punch anything that gets too close to her. She's even went so far as to attack Sari on many, many occasions just for being around (Much like Sari herself was with Martin). Nonetheless, she does care for her friends and would happily fight on their behalf. She was banished to the TARDIS for a while for her bad behavior, and very well may still be there to this day. No one knows what really happened to her after Oblivion crashed and the Tale was switched to Elder Scrolls Online, since the actual lore was never confirmed by Venturian and just left up to the fans to theorize about.
