Spoilers for Episode 5 of Game of Thrones follow. Proceed at your own peril.

Last night’s episode of Game of Thrones managed to sneak in a major reveal for the hit HBO series that’s likely to become a major game changer in the episodes to come.

During “Eastwatch,” Gilly (Hannah Murray) asked Sam (John Bradley) what an annulment meant (much to his annoyance). She then proceeded to say the annulment was made by a Septon for a certain Prince Rhaegar (Targaryen) so that he could marry another woman. In secret. In Dorne.

Although Sam didn’t catch on to the true significance of that revelation, since he totally (and rudely) interrupted Gilly before she could name the other woman in question, the audience did, sending them into a frenzy (we've included a few Twitter reactions below).

What this means is that Jon (Kit Harington) seems to be the legitimate son of Rhaegar Targaryen and Lyanna Stark (something Bran already knows); meaning he’s no bastard but a true Targaryen (if Drogon allowing Jon to pet him wasn’t confirmation enough) and the legitimate heir to the Iron Throne. Oh, and that makes Dany (Emila Clarke) his aunt.

Since Jon is the direct male heir, his claim takes precedence over that of Dany’s, who has no idea she’s not the only Targaryen left (neither does Jon, for that matter).

What did you think of last night’s new near-confirmation that R+L=J? As promised, here are a few Twitter reactions:

And here’s the one from über Game of Thrones fan Leslie Jones:
