Elizabeth "Lizzie" Wemyss

Lizzie Wemyss arrives at River Run as a young indentured servant, assigned to wait on Brianna and help her navigate an unfamiliar colonial world. She's small, watchful, and quietly devoted, prone to fits of fever that leave her frail, but her loyalty and good humor make her more companion than servant almost immediately.

O'Ryan plays Lizzie with an unforced sweetness that never tips into simplicity — there's real intelligence behind the deference, a girl reading her betters carefully to survive. The role gives Outlander a window into servitude from the inside, and Lizzie's genuine warmth toward Brianna makes their friendship feel earned rather than written in.
