Introducing everyone to my Alastor headcannon!
He's a deer right? And what are deer well-known for? Yes, yes, staring un-waveringly into your soul in the middle of a country road in the twilight hours.
But what else are they known for?
As soon as something happens, they are GONE. They run so fast and with such wild-abandon to just get the fuck out of wherever they are they they go hurtling through the brush never to be seen again.
This brings my to my head cannon - Alastor is easily skittish, he is just fortunate that his deer-caught-in-headlights instinct takes over long enough for him to grapple with his fear and restrain the part of himself that wants to flee, so instead he just stares unwavering and intimidatingly with that cocky grin until he has enough composure to begin talking again.
Now, sometimes, sometimes his instincts are too strong. And sometimes, he cannot stay composed, especially after a particularly bad fright, like bumping into Nifty or Angel Dust stalking the corridors of the hotel silently at night. What happens then? Alastor freezes for mere seconds, and then goes hurtling as fast as he can in whatever direction his feet decide to take him.
Sometimes, much to his dismay, his feet decide to propel him into the nearest wall before he even realises where he is heading.
This has led to many encounters where Alastor appears to bolt head-first into a wall for no other explanation than he felt like it, and he leaves Angel Dust as confused as ever as he bounces back from the impact, shocked from his deer-like-terror, and begins a conversation as normal, ignoring the new antler shaped hole in the wall he had just careened into.
No one dares question him about this odd behaviour, and the residents of the hotel have just had to accept that they often see the sole's of his shoes as he sprints full-pelt away from them at the drop of a hat.
