Eavesdropping on the conversation, we see/hear Jaina, Derek, and Calia inside a building in Seabreeze Village, Stormsong Valley. Jaina and Calia are next to each other at the start, with Derek walking to them having come from upstairs.

Calia Menethil: Ah, Jaina. What a relief to see you safe.
Lady Jaina Proudmoore: Hello, Calia. Big brother.
Derek Proudmoore: Word has spread of what happened at Orgrimmar. Is the war finally over?
Jaina: It will take time for all the pockets of fighting to be quelled, but... yes, I believe so.
Calia: Azeroth has seen so many wars, so much strife. I pray we have earned a respite.
<Calia moves to Derek and they hug one another as Jaina speaks. They turn and face her for the rest of the conversation, standing close to each other.>
Jaina: As do I. Have you been able to find peace in your own heart, Derek?
Derek: I still have some rough seas to sail, but I'm much better now, thanks to Calia. Without her guidance, I would have been truly lost.
Calia: I'm so grateful you brought us together, Jaina. This time with Derek has helped me as much as it's helped him.
Jaina: In the wake of this war, others will need to find their footing. Their future. Perhaps you could guide them, too.
Calia: I'm not sure how much help I could be. I don't have all the answers.
Derek: Maybe they don't need answers. Maybe they just need hope. Like I did.
Jaina: Well said, big brother. Come, let's take a walk. I am so grateful to have you both back in my life. Let's enjoy this moment together.
<Jaina exits the building.>

After the conversation, Jaina leaves the village and fades away. Calia and Derek remain in the building, seemingly friendly to Horde players.
