"Winter is coming" aside, HBO's "Game of Thrones" hasn't become a catchphrase machine, but if the TV series follows the path of the books, that may be about to change, thanks to spunky wildling Ygritte.
 
The character's condescending-yet-affectionate "You know nothing, Jon Snow" is one of the most frequent utterances in George R.R. Martin's "A Storm of Swords," but it's only begun to be heard on the HBO series. 
 
On the red carpet at Monday (March 18) night's "Game of Thrones" season premiere event in Hollywood, I caught up with Rose Leslie, TV's Ygritte, to talk about the fine art of "You know nothing." Leslie also discusses her newly discovered gift for archery and speculates on what her long-absent "Downton Abbey" character has been up to.

"Game of Thrones" returns to HBO on Sunday, March 31.
