quick question: how rare is it to be "captured" by him?

i were playing gm_construct, when i were in the corridor between the place behind the spawn and the building on left, there was a few props and 2 sprays, i spawned a seagull and i've seen his model walking towards me then the only thing I saw was my crowbar and a black void.

i forgot to take prints, lol.

today's lesson: never try to kill a seagull from a thin, burnt man.
