After watching Thor: Ragnarok (*coughfourtimes*) I’ve decided…
Loki in Thor: *looked like a cinnamon roll but could actually kill you*
Loki in Avengers (and maybe TDW a little still): *looked like he could kill you and would kill you*
Loki now: *looks like he could kill you but is ACTUALLY A CINNAMON ROLL TOO PURE FOR THIS WORLD*
….that is all.
