Unfortunately, if we decide to show Christina, we'd have to recast her. Jordyn Negri, who played her in the WH2 episode flashback scene, is 17 now. She was either 10 or 8 when she died (8 according to her coffin, 10 according to some other source I can't remember). I think the dates 1883-1891 work the best, since the alternative would be '91-'99, and that conflicts with the rest of HG's and the Warehouse timeline by extension, I think. 10 year olds might be better to work with than an 8 year old, I'm sure, and it would be a good chance to get an actual British actress to play her (Jordyn was born in Canada).

Another thing I realize is that, as of the auction, I'm not sure whatever prop house may or may not store props would have a copy of Helena's locket. It was sold on ebay, and I can't remember if there were multiple copes of it made. If not, reproducing it might be difficult if not impossible, since I'm not sure if it was made for the show or purchased from somewhere. A lot of props might need to be reproduced or cut out altogether thanks to the auction, come to think of it.
