1. Jon Snow was startled by a dragon right after proclaiming he wasn't a Stark — foreshadowing much?
Jon Snow (Kit Harington) was stunned by the sight of Drogon.
Most of the fandom knows by now that Jon Snow is actually half Targaryen. His father was Rhaegar Targaryen (Daenerys' brother) and his mother was Lyanna Stark (Ned Stark's sister). The shock of his first encounter with a dragon felt like a nod towards audience members in the know.
His blood relation to Daenerys is part of the reason fans are against the idea of a romance blossoming between Jon and Daenerys, but Targaryens are known for their incestuous relations.
2. The Dothraki man overseeing Jon and Davos' arrival is the same one who first brought Daenerys to his khal as a captive.
Staz Nair plays Qhono.
Qhono (played by Staz Nair) is the Dothraki character who took Longclaw from Jon Snow when Missandei requested the Stark emissary relinquish their weapons.
If he looked vaguely familiar, Qhono was a prominent part of Daenerys' time as a Dothraki captive on the sixth season.
Qhono was extremely disrespectful towards Daenerys.
Qhono has come a long way since threatening to rape Daenerys Targaryen on the sixth season — now he's one of her most trusted Dothraki soldiers. The Mother of Dragons had him on the beach when Jon and Davos arrived, and then later ordered him to show the "guests" to their chambers.
3. We also got more exposition about Daenerys dragons and how their names relate to important men in her life.
Daenerys told Jon that Rhaegal and Viserion were named for her brothers.
Non-book readers may not have realized the meaning behind Daenerys' choices for her dragons' names. Her three dragons actually each have distinct coloring that relate to their names.
Their distinctive coloring were more noticeable when the dragons were smaller.
Drogon, Rhaegal, and Viserion as baby dragons on season two.
Drogon — the biggest and most fierce of her dragons — is black and red. He's named after Daenerys' first love, Khal Drogo.
Rhaegal is green, named after her brother Rhaegar — and Jon Snow's father (though neither of them know that bit yet).
Last, Viserion is described as cream and gold colored. He's named after Viserys, Daenerys other brother who was killed by Drogo with molten gold.
