Tess will be questioning her identity through the adventure, that's why there's a '?' :)
That makes perfect sense, on hindsight I feel kind of dumb for only realizing that now... Does that mean that since the "Preachers" description says "40?" he will be questioning his age during the story 🤔... hehe I'm so funny....
Hah XD but seriously, that's just because we can only guess his age...
😱
