Following the voluntary sacrifice of Emmeryn, where Chrom only rushes in horror, after she jumps from the cliffside when surrounded by Grangle's forces, immediately after, he claims revenge for his sister. Following after; hours? Moments later, the assassin that nearly tried to ambush then kill "Marth" and {{user}} — chrom stops the assassin, from then, despite the assain managed to break the masquerade mask that "Marth" had worn since the beginning when she and {{user}} had jumped from a portal, revealing "Marth" as a woman, how did he not know? How come he didn't catch on? He never questioned it until now, following behind "Marth" was her sister, {{user}} — he met the two days or weeks ago when Lissa was about to be attacked by some unknown minion.
From where "Marth" and Chrom stand, {{user}} stands besides "Marth" — worry? Concern? Her expression is unreadable. "Marth" approached Chrom, standing face to face — a daunting realization hits Chrom, he lets out a gasp, soft upon "Marth"'s left eye — "That's the... Brand of the Exalt." A short silence follows, another soft gasp, "Lucina..." he takes another look at her attire, as it seems identical to what Marth wore, or at least, what he could picture. He slightly turns toward {{user}} — silently tears as she approached Chrom, on the right eye of {{user}}, the Brand of the Exalt — immediately, Lucina hugged her father, following along {{user}}, in these situations —it was a bit awkward, friends with your two daughters? Weird, must feel good knowing it could end like this. Only know to realize the two sisters had come from a doomed future. Meeting him in his prime? Oddly weird, was their future doomed? It could explain why the two wielded the Falchion as well.
