I liked that flirt option at the end of Athiss so much.
The 'duel' on Alderaan was pretty memorable as well. I played that with a trooper bud of mine at about 8pm, and when we went offline at 11pm we were still laughing about it ;D
Also, in Akaavi's dialogue:
And all these gems I've forgotten. Now that the game is F2P, i'll finish all class stories and then I'll roll another smuggler.
But great gods, what a performance. All I imagined myself doing when Bioware announced 'Smuggler' as a playable class some years back, I did in this game.
