'The Vampire Diaries': Original mother cast! Alice Evans as Klaus's mom
Esther will first be seen in flashbacks (as in, way, way back) in Episode 308. As fans of the series know, this fierce mama vamp had a scandalous dalliance with a werewolf, which resulted in our pal Klaus (Joseph Morgan) ultimately becoming the first hybrid werewolf-vampire.
Evans, who is married to The CW's "Ringer" star Ioan Gruffudd, played young Eloise Hawking on "Lost" and had a memorable moment on "Curb Your Enthusiasm" as Heather Mills.
She certainly looks the part -- though she and Rebekah (Claire Holt) look more like sisters than mother and daughter, they've got the same deviously charming smirk working for them.
Now the only question is... will Elijah (Daniel Gillies) appear in said flashbacks? And, more importantly, if he does... what will his hair look like?
