Cullen doesn't consider himself a romantic, has always been far too practical for that kind of nonsense.
He changes without even noticing.
The idea comes to him when he sends his men out to gather herbs in the Emerald Graves.
He slips a note in with the list of the resources they are to gather, a list that asks for wildflowers.
If his men think it strange, they say nothing, and they return with a large boquet.
He places them in her room himself, on her desk, the day she's expected back from the Hissing Wastes.
Cullen doesn't see her that day, but when he's called to meet in the War Room the day after, she has braided her hair and decorated it with some of the flowers he gave her.
No one says anything, and Cullen is too busy looking at Lavennan - who's looking over the reports - to notice the glances that pass between Josephine and Leliana.
So it becomes a ritual; whenever she is away - which is too often for his liking - he sends out someone to gather flowers for her if he can't do it himself.
If his men are sent too far away to be able to bring back fresh flowers, he tells then to press and preserve them so there can always be a part of nature in her room, even if it can't always be fresh.
If Lavellan suspects anything, she never tells him.
And it's okay; he doesn't need for her to say anything, doesn't need to hear her say "thank you".
The smile on her face and the flowers in her hair when she comes out of her chambers are enough
