HBO's hit drama series debuted its second-to-last episode, "The Bells" on Sunday evening. From Daenerys Targaryen's sharp turn towards a dark path to the epic "Cleganebowl" fight and death of Cersei and Jaime Lannister, it was a packed 80-minute episode.

Even before the episode began, the "previously on" segment had a series of important context clues.

Signaling the dark turn the Mother of Dragons was about to take, showrunners Benioff and Weiss selected a set of seven lines from previous episodes which all showed the internal conflict plaguing Daenerys. 

The pieces of dialogue were all centered on the tormented Targaryen legacy.

We heard quotes from Dany's best advisers over the years, as well as a few choice lines spoken by her enemies or, in the case of Aemon, relatives she never met. 

Here's every line and the episode it was pulled from:

• "Every time a Targaryen is born, the gods flip a coin." — Cersei Lannister (season two, episode seven)
• "The Mad King gave his enemies the justice he thought they deserved." — Barristan Selmy (season five, episode two)
• "Children are not their fathers." — Tyrion Lannister (season seven, episode three)  
• "Be a dragon."  — Olenna Tyrell (season seven, episode two) 
• "You have a gentle heart." — Jorah Mormont (season two, episode five) 
• "A Targaryen alone in the world is a terrible thing." — Aemon Targaryen (season five, episode five)
• "You don't want to wake the dragon, do you?" — Viserys Targaryen (season one, episode one)

The opening credits changed ever so slightly again.

In tradition with this season's ever-changing opening credits, the gates of King's Landing got a small upgrade for the start of "The Bells."

Two small scorpions (those massive, dragon-slaying crossbows) popped up on either side of the main gate. Those didn't appear on last week's episode, "The Last of the Starks." Now that Daenerys destroyed them all, we're sure the credits will change yet again for the finale.
