I was a bit worried when they brought back 1893 in the tag and H.G. and Wolcott were casually walking down the street talking about the case and the Warehouse, but nobody popped out of the shadows or anything so he officially survived! Plus, he got top billing over the 1960's team, who were actually featured in an earlier episode (I think they were both the same actors), if that means anything. However, it doesn't seem like that actual time period (after what happened to her daughter) fits in with the spin-off plans, but maybe it could be a recurring thing in Warehouse 13 for the next time they need H.G. to help solve an old case.
