Game of Thrones is chockfull of characters who don’t see eye to eye, but one of Sesame Street’s most beloved characters is hoping to change that!

Two very different worlds collided on Thursday (January 18) when Sesame Street’s Elmo paid a visit to King’s Landing to try and sort things out between sibling Cersei and Tyrion.

The aim of the unlikely crossover? To teach the Lannister siblings that learning to listen and respect each other can go a long way.

“Respect brings ups together, and if anyone can convince @GameofThrones’s Cersei and Tyrion to get along, a familiar furry friend might just be the one,” tweeted the long-running children’s series.

The short clip, featured in the tweet finds Cersei and Tyrion having a tense conversation. It’s not long before they’re joined by Elmo of Sesame Street.

“Elmo thinks that you two need to respect each other,” he says. “When Elmo has a problem with friends like Abby or Cookie Monster, Elmo doesn’t get upset. Elmo listens and learns from what they have to say.”

So how did Cersei and Tyrion take Elmo’s advice? Watch the clip above to find out!

Here’s hoping Cersei in particular heeds that advice — especially with the Night King and his army closing in!

Game of Thrones returns with its second episode of the series’ final season this Sunday at 9 p.m. ET on HBO.
