Game Of Thrones Season 7 Trailer Breakdown: 35 Things You Need To See
28. Iron Throne
Cersei greets... someone in her Throne room. It's not easy to make out just who this is, but really there are only a few possibilities. One is that it's Mark Gatiss' Tycho Nestoris, who is returning for Season 7. That would mean the Iron Bank paying the new Queen a visit, which would make sense given the debt owed to them, and explain why neither Cersei nor Jaime look happy.
The other possibility is that it's Euron Greyjoy, with a haircut, coming to make a case for an allegiance in order to stop Daenerys. That team-up is something that could well happen in Season 7, so it's certainly plausible, and would again be a suitable explanation for Jaime's face here. He's not gonna be happy with another man coming in with a (potential) marriage proposal.
Cersei, meanwhile, looks like she was made to sit on that Throne. I think it's the outfit, which is just totally badass.
