I was looking through your Rose Trevelyan tag and I stumbled down upon headcanons for her parents Gareth and Grace - who are awesome and I want them to sign my Mage staff ohmygod so cool. Anyways, I was wondering how do they respond to Cullen? I want to assume well but what's your take?
Someday I very much hope to fic this, actually.
So, the short(ish) version is once Rose starts sending letters to her family (as in Letters Home), a very steady correspondence is established. Rose doesn’t hold back much. (Leliana–and Josephine, for that matter–live in a constant state of terror that Rose’s letters will fall into the wrong hands, since she rambles on in detail and at length about whatever’s on her mind, sensitive information or not.) So, Grace is privy to a lot of information about Cullen, and is very much predisposed to like him.
Which doesn’t mean it’s going to be greeting him with open arms when she finally gets to meet him. Oh no. Grace doesn’t trust easily. She trusts her daughter, but prefers to take Cullen’s measure on her own, in person, just to make certain Rose hasn’t been taken in… via very polite and very pointed interrogation, the likes of which Cullen has never experienced. Grace is exceedingly good at polite interrogation.
Rose is mortified, but Cullen passes with flying (if occasionally stammering) colors. (Grace is, truth be told, so very amused by flustering him that she may drag things out a little longer than strictly necessary. Besides, she has to find out what kind of sense of humor he has. And whether he’ll fit into a family that teases each other mercilessly.)
The thing with the letters, though, is that Gareth never writes. Rose gets letters by the score from her mother and her sister, but her father is silent. She’s confused, and a little hurt. Her mother passes along messages–”Your father says hello, my dear one, and apologizes for leaving all the conversation to me. You know how he is,” or “Your father’s been training a bevy of new archers. Do you remember how awful your aim always was? Maker, we’d never seen anyone so incapable of hitting a target. Astonishing. I’m glad you have no such problem directing lightning bolts. He sends his love.”–but Gareth doesn’t write himself.
After the battle with Corypheus she finds out why. As soon as Rose’s first letter reached them in Ostwick–the letter where she asked them not to ‘careen all across Thedas to help’–Gareth… careens all across Thedas. And anonymously joins her army. They need people. He’s beyond skilled with a bow. And though he may have inherited some nobility through marriage, he’s still a common man at heart, and fits in effortlessly. He never interferes with Rose’s life, but he does watch over her. Not, he finds, that she needs it. In the course of things, it stops being about watching over Rose. He starts believing in her cause, in her. He gets to be a part of it all. (Grace, it should be noted, is wildly envious, but as she is the one with all the responsibilities of the Bannorn, she cannot simply up and leave and join Inquisitions and such. More’s the pity.)
Rose has no idea her father’s been essentially right under her nose the whole time. Consider the outing with the Iron Bull, when the Inquisitor meets some of the soldiers who have no idea who she is. The army is big; she doesn’t know everyone; and talented or not, her father’s just another archer in a sea of archers. And Rose is a terrible archer, so it’s not like she ever wanders down to the practice butts herself.
What this all means, though, is that Gareth knows Cullen in the context of Commander–his Commander–while also being privy to all the Skyhold gossip. So, Gareth does everything within his power to ensure he never pulls guard-duty near either Cullen’s quarters or Rose’s (some things a father does not want to be privy to, and the gossip is bad enough), but, because of his unique perspective, essentially never in all of history has a (potential) father-in-law so approved of a daughter’s choice.
