DA:O (lawd there are too many I could list here)
-Dalish Warden leaving her clan
-Battle of Ostagar
-Zathrian breaking the curse. One of my most memorable tracks in the series for it. Goosebumps.
-Morrigan's friendship with a female Warden, where she comes to regard you as a sister. Particularly, the final scene at the gate. Claudia Black nailed that last line. "I knew nothing of friendship before we met...but know I shall always consider you such. Live well, my friend. Live gloriously."
-Oghren's last scene was pretty great too. "Let's show them our hearts...and then let's show them theirs!"
-Female Dalish meeting Tamlen again
-Earning Sten's respect.
-Leliana's romance as it progressed. My inner sap was getting feely. "I will never regret leaving Orlais. I will never regret any of the pain, the anger, the loneliness, because it brought to you. And I...love you. It's so wonderful to say that to someone again."
-Dueling Loghain
-Warden letting out a triumphant battle cry as she slew the Archdemon
-The final coronation. It's always such a bittersweet feeling when I get there. Sometimes I don't want to go out of the doors to the epilogue. :C
DA2
-Meeting Varric
-A plethora of sarcastic Hawke moments. "I have an excellent sense of dramatic timing. And good hair."
- Varric/Sarcastic Hawke bromance moments
-Marethari's death
-Leandra's death. Felt it was pretty poignant with my sarcastic blood mage Hawke. He had no jokes at that point.
-Full rival Templar Carver still stepping in front of Meredith when she was going to kill his sibling. They might be at each other's throats often, but he's still loyal to his family. It's why I liked Carver the best.
DA:I
-Leliana's crisis of faith. Her mentions of a romanced Warden as basically the last light in her life. The Warden's letter begging the Inquisitor to help her see the light again, and then doing so. Blegh feels.
-In Your Heart Shall Burn. All of it.
-The Envy Demon's nightmare.
-Besieging Adamant
-Comforting Varric after Hawke's death, Varric's story about them afterwards.
-Solas' romance, in all of its gut-punching glory.
-Flemeth, Morrigan and Kieran's family reunion. The way Flemeth actually seemed legitimately touched at how much Morrigan seemed to care for her son, and her face when she said 'he would be better off without me, just like I was better off without you...'
-The final, post credits scene with Flemeth and Solas.
