Rose MacClare (Lily James) just can’t help herself from having a good time. The young Scottish beauty has a passion for life, but she’s never been able to fully embrace it at home with her stodgy parents Hugh and Susan, the Marquess and Marchioness of Flintshire.
Whenever she can find her way to London, however, expect to catch Rose listening to jazz albums, dancing the night away, and consorting with gentlemen (and not so gentle men). Now that she’s living with the Crawleys while her parents gallivant around India, we can expect Rose to get into even more trouble.
Rose was introduced in Season 3, Episode 8.
