U, I, T
U: is the most unapologetic for the way they live their life.
Loriavoth, 100%. He has no shame in the fact that he is a walking disaster and his living quarters match. Baths happen rarely, yet he marches around like his stink isn’t in fact the biggest insult to the noses of anyone and everyone within a thirty-six foot radius. No shame in his life choices, none.
I: tends to idolize people they shouldn’t.
The closest one to idolising people at all is probably Billy. He has a very black and white outlook on other people; either they’re perfect and can do no wrong, or are awful with no redeeming qualities who need to die. So either he’s going to think someone with flaws he’s yet to notice is the best ever, or hate a completely ordinary person for a single flaw he does notice.
T: is the most terrifying.
Milo or Nehmoras.
On the one hand, you have a man who on his own managed to bring Scourge undead back to sentience (only one, but had he not died, he likely would have done the same for others), but also persists in using the Light in death and pushes through pain no matter where it comes from.
And on the other hand, while he’s currently unaware of his own potential, Nehmoras is capable of gaining anyone’s memories should he bring them harm or kill them, change those memories however he’d like (not that he would), and has more than a couple ways of completely puppeteering someone against their will.
There is a reason he can’t reverse his own memory issues: the source of its doing was very, very good at what they did.
