Dain’s signet means people are afraid of being touched by him. Sloane’s signet means she’s afraid to touch other people.
They are each others balance.
A first year in Fourth Wing (a marked one he was warned about of the rebellion he was raised against) & the third year Wing Leader whose father is responsible for killing her brother; making them “should-be-enemies” yet, they have impeccable chemistry. Challenging each other as one of them was rather by the books (but is slowly fraying/changing) and the other a walking rebellion, pushing them into the gray middle ground; creating a balance between them. From the moment one first says, "I’m going to hurt you" & the other "gods don’t I know it" —
… Much like "You’ll be the death of me & "she’d be the best thing that ever happened to me, I’d be the worst thing that ever happened to her" … sound familiar?
Making them the balance to the last time this happened.
Their signets are the balance, and may very well change the war… Her siphon as a signet which could be the counterpart to the Venin; as instead of draining life, she is “life”. And where a main character is now missing (what may be) crucial memories, his signet allows him to find and see memories; which could help if they don’t wish to be found.
They are the balance.
