So how DID Eliza end up in Mando's time?
Eliza went to a state park to go hiking, and while walking on a trail, she suddenly found herself on a tropical island in the Caribbean. A sort of blink and you’re elsewhere kind of thing.
Only she wasn’t in modern times anymore, this was the 1750’s. A few months were spent doing odd jobs before she ran into the vampires of the Silent Mary.
