In the World of Ruin, Noct casually mentions how nicely Talcott has filled out. The bros can't believe he just fucking said that out loud (especially after they've been silently thinking the same thing for like months/years and trying not to be weird about it). Talcott can't believe that the hero(es) he idolized might be more within reach than he ever expected.

If there's smut, please no daddykink. "Big bro" stuff is A-OK, though ;)
