It’s better late than never to catch up on who’s who in “Game of Thrones.” There are a lot of new characters that have already been introduced in Season 3, and now a featurette has been released that gives viewers some background and context for each of them.

In addition to information about people like Mance Rayder, Lady Olenna and Missendei, the video also includes a lot of new footage. The featurette teases a showdown between Olenna and Tywin Lannister — she is the one to finally snap his quill! — and that Melissandre will come visit the Brotherhood Without Banners. This also gives fans their first in-depth look at Richard Dormer‘s Beric Dondarrion and his upcoming duel with the Hound.

The characters focused on in this 10-minute-long video are Olenna, Missendei, Mance Rayder, Tormund Giantsbane, Orell, Jojen and Meera Reed, the Blackfish, Edmure Tully, Thoros of Myr and Beric. If you wanted a quick catch-me-up on any of them and Zap2it’s “Game of Thrones” who’s who gallery isn’t enough, then this featurette is definitely worth watching. As showrunner D.B. Weiss says, “We’re still casting more than we’re killing” at this point in the series, so it’s wise to know who you’re watching on the hit HBO fantasy show.

“Game of Thrones” airs Sundays on HBO at 9 p.m. ET.
