Favourite romance?

A have a strange feeling that if Blooming Rose got honorable mention as well, even as a joke, it would have more votes than him.

She does call Hawke the cute nickname Honey Badger if you sleep with her so I rank her as higher than Sebastian tbh.

Not that Sebastian is bad, just not to my tastes personally.

I couldn't vote since it is a tie between Anders, Fenris and Isabella. I like those equally well. I didn't do the other romances, since I'm not fond of Merrill and Sebastian (they are onl for comical relief in my parties)

You're a nice person

Friendship romance with Fenris wins out, though second place for me is friendship romance with Merrill.

Sebastian.

Because first... I DO WHAT I WANT.

...And secondly, I actually like what little there is. And the implications for my headcanon. To some extent, Sebastian is actually the most chill and least problematic of the love interests. I usually have low melodrama tolerance, so friendship Sebastian is right up my alley. Also, tragically, he's probably the closest I'll get to flirting with Nathaniel Howe, and while I'll never let that stupid vidja game crush go, I'll accept the substitute.

And archers have great shoulders.

I felt like all the "romances" in DA2 were pretty minimalist and it didn't help that most of the romanceable companions were pretty bare-bones too. But for story purposes, at least, my canon Hawke romanced Anders, and I feel like it was the best "fit" to the story, even if it doesn't really make a difference in how the story plays out.

Isabela is my Hawke's canon (with Sebastian as a close second). Not knocking on the other romances. I've done them all and they're all good in different ways, but I like Isabela's general care free nature and how easy going she is compared to the others.

Isabela.
Why? My first few games were either Anders or Fenris, sometimes Fenris then Anders after Fenris abrupt dumping. I even had a Fenris-->Isabela-->Anders pt. I have to admit, for a long time I was blinded by the voice (Fenris, of course). I have a Merrill romance somewhere, and a rivalmance with Sebastien. What I didn't like about Sebastien is that he will only be with you if you become Viscount. He says as much. And I don't know if I can play a Hawke pious enough to settle for a chaste relationship within the Chantry. Merrill is, thanks to graphics design and character, too childlike for me.

After a while I got tired of Anders and Fenris. By Act III they were in a bicker rut. "Mage freedom" or "Mages are evil" (especially annoying when Hawke is a mage). I felt they stopped growing as characters. The ending was nice, but you have to get there first.

Isabela is the one, imo, who grows the most. She starts out carefree and careless, she leaves out of self-interest, but she can come back (out of either love or friendship). Love and commitment scare her. She doesn't think she's good enough to be with you. She is loyal, whatever you decide.

Eh, Fenris more than mage-hater. But true, he really fears from the mages/magic. In friendship, he kept a part of this fear, and in romance this is really annoying (I imagine, that Hawke constantly feel, that Fenris fear from him, and still hardly accepts his ability), but in rivalry he will ba able to get rid from his fear (at least not so annoying). No matter, at Gallows he only enthusiastic in the fight, much more enthusiastic than Varric at mage side. He concentrates only the fight, not the evil mages. I saw his conversation at the Templar side... there he still concerned about the mages...
In friendship, without romance, he's really sweet: after the Alone quest he just hoping, that can stay at Hawke side in the future (haha, I like to imagine, that he join to Hawke and Anders to free mages after they leave Kirkwall! Headcanon!). In rivalry without romance, he still doesn't blame the magic/mages anymore, and apologizes if it was difficult with him, only a bit colder than in friendship. 

He doesn't consider the mages "evil", just fear from the weak mages, who can't resist the temptation of more power. The best scene about him, if Anders kills Ella, and he warns Anders, that he's dangerous. In this scene, he doesn't condemn Anders, just warns him. At Gallows, he agreed with Hawke, that not all mages are evil, even along the Magisters there are good, noble people, who can resist to the temptation. He only fears from the human weakness, than the "mages, just too hard to leave his old life behind.

And Anders so single-minded? This is not really right, because, for example, he cares about the refugees too, but later in Kirkwall the situation so hard, that he's can't ignore this, and I don't believe, that the reason is only Justice. 
But you're right about him: he's not "grows" because he doesn't need to grow. (If we can't call growing, that Justice doesn't cause more problem after Ella's case.) In rivalry he not only not grows, but regresses and become a miserable uncertain man, who blames Justice for everything, and hardly control his mind: Justice is a problem, because doesn't understand, what happened with Anders, I think.

Anders can't leave his problem behind, because the problem is around him, everywhere in Kirkwall. Fenris can leave his problem behind, because his problem's one part is dead, the other parts left in Tevinter.

And Isabela? Yes, she become a better person, because finally she found friends, and her problem is dead.

Why Anders' selfish? He have many flaws, but he's not selfish and loyal to his cause until he dies, or win.
