5 important things you probably missed on this week's 'Game of Thrones'

Warning: spoilers ahead for Sunday's episode of "Game of Thrones,""Book of the Stranger."

There were some major (and much-anticipated) reunions on this week's episode of "Game of Thrones."

The biggest one for fans finally found part of the remaining Starks coming face-to-face after fleeing Winterfell. Sansa Stark (Sophie Turner) and Jon Snow (Kit Harington) met up again at Castle Black.

They weren't the only brother-and-sister pair to meet up again after great struggle. Imprisoned Margaery (Natalie Dormer) was rewarded for her calm demeanor and knowledge of the ancient text. So she got to join her brother Loras (Finn Jones) in his cell for an emotional conversation.

Meanwhile, Daario (Michiel Huisson) and Jorah (Iain Glen) finally made it to the Temple of the Dosh Khaleen, where Daenarys (Emilia Clarke) was about to go on trial in front of the Dothraki leadership. Well, that got heated...

That's the stuff you couldn't help but notice, but there's always plenty that you didn't catch.

Here are five important things you probably missed on this week's "Game of Thrones":

Sansa and Jon's first words to each other.

Yes, Sansa and Jon were raised as half-siblings at Winterfell, but have they ever actually spoken to each other? The answer logically is, of course, yes. We know that from the episode when Sansa asked Jon to forgive her for treating him cruelly while growing up.

But would it surprise you to hear that they've never spoken to each other on-screen in the history of the show? If so, put your surprise face on. This episode was the first time they've exchanged dialogue. Those history-making words were Sansa's: "Good soup."

Tyrion's slavery compromise was inspired by Abraham Lincoln.

If you felt like there was something very familiar about Tyrion (Peter Dinklage) offering a compromise of phasing out slavery over seven years, then you were on to something: It was inspired by our 16th president, Abraham Lincoln.

"One of the historical examples we looked to while writing these scenes was, oddly enough, Abe Lincoln," showrunner David Benioff said in the "Inside the Episode" segment. "Abe Lincoln was trying desperately to stave off a civil war between the North and the South, and he wasn't ready to get rid of slavery quite as quickly as people think."

Did Osha go too soon?

Osha (Natalia Tena), the faithful Stark servant and dangerous Wildling, gave her life trying to kill Ramsay Bolton (Iwan Rheon) on this episode. Her plan to seduce and stab him dead went awry. At this point, we're not sure if George R.R. Martin gave the showrunners a little bit of information as to how she died, or if that was simply the show's plan. At any rate, she is still alive and protecting Rickon Stark in the books. Guess we'll have to see where Martin takes her.
