Merril might go , first we have no bloody idea what Solas is telling the elves ,he lied to us the whole time in Inquisition just because he wanted his Ball of Doom.
And no not just "by omission" like he claims in Trespassers."Oh jeez Cassandra I've never seen any magic like this before the Breach , and I tell you the truth : I don't know any mage who would be able to have this power./Trollface."
Merrill is jut going to pee herself with joy if she met Solas .He's not afraid of magic , spirits , he knows Eluvian and he's an ancient elf
And he wants to restore the elves , so they have the "Gift " back.
Also Solas :"Jeez the Dalish are stupid , they weren't listening to me when I was telling them I was right and they knew nothing."
Merrill "Oh you too! My clan didn't listen to me with the Eluvian, they thought I was bringing doom upon them!"
Solas "Pfff , I know Merrill , you say you want to rebuild an Eluvian or tear down the veil and everyone is suddenly having vapor because they're too stupid to understand."
No seriously if Solas skip the part of the world burning in raw chaos , Merrill would probably end up his BFF.
