Necromancer who can turn himself into a ghost Thomas. And asexual Thomas because I like this headcanon. ^^

And he was like I don't really have time for romance and stuff in with WICKED and all the happenings. Do you see my point? Also let's be honest being demiromantic can make you a little oblivious of your romantic feelings kind of. So obviously he was kinda oblivious of his own feelings for a certain person (cough cough, Newt). But that's a story for another day. Thank You!!

he’s sees all these other people with Urges and is very confused why he doesn’t get that, too. he thinks people are pretty and he feels a Thing in his chest when he looks at a certain person, but it’s on a different frequency to what most people feel. he’s tuned into things slightly differently (and completely tuned out of other things).
