One of the most crucial characters to the Game of Thrones storyline is Rhaegar Targaryen. The funny thing is that viewers have never actually met the prince because he died… but not before secretly fathering one of the major protagonists of the show: Jon Snow. Now, fans are theorizing that the character will finally be introduced in a flashback during the Season 7 finale — "The Dragon and the Wolf" — but, who will play him?

In case you're wondering how Rhaegar fits into the current plot, don't worry, you're not alone. The late Targaryen is Daenerys' older brother who was killed by the late King Robert Baratheon. To make a long story short, Rhaegar was married to Elia Martell, but fell in love with Lyanna Stark (Ned Stark's younger sister) who was engaged to Robert. Still following? We found out last season that the R+L=J theory is right meaning that Jon is Rhaegar and Lyanna's son. And even more importantly, we found out this season that the lovers were married, meaning that Jon is not a bastard and has a rightful claim to the Iron Throne. Watch the video below for scenes about Rhaegar from the show!

Of course, fans can't be sure that Rhaegar will make an appearance in the Season 7 finale, but it's highly unlikely that we will never see him. And let's face it, we're all dying (no pun intended) to lay eyes on the silver-haired prince who stole Lyanna's heart.

And we might not have to wait much longer. Fans already think they know which star will play the character. Redditors believe that Welsh actor Wilf Scolding could play Rhaegar. First, actress Aisling Franciosi (who plays Lyanna) began following him on Twitter when Season 7 was in production last September. He is also following Liam Cunningham (who plays Ser Davos) on Twitter. They also added that GoT has a habit of casting unknown or first-time actors. Sure, this could be a reach, but so are fire-breathing dragons, so just let us have this one, okay?

And honestly, fans don't need any more convincing. His Instagram comments are already full of Rhaegar mentions. "I think he'll be Rhaeghar too. He looks like an older Viserys," one fan wrote, while another added, "I am going to cry with happiness if this is Rhaegar. We the fans have waited soooooooooooooo long to see him on screen."

So, don't break our hearts, Wilf. Be the Rhaegar Targaryen we need you to be, because honestly, you already look the part.
