Solas and Felassan were obviously close, in a way that I personally see as hard to define between friendship and romance. Whatever you want to call it, their love for each other was obviously very strong.

We don't know for sure why Felassan kept his vallaslin. His most well-established trait is his value for freedom, so I figure there must be a motive within him somewhere to keep what in his day were slave markings. And so I thought, maybe he uses them as a symbol of rebellion in his own way.

Amaris, meanwhile, sees the vallaslin as having been reclaimed and given a new purpose in modern times: marking her as Dalish. Because her biggest fear is assimilation, it means a lot to her to carry that recognition of her culture. So in a way, she too uses it as a rebellious purpose.
