you saw syzoth or known as reptile in his reptilian form and he spotted you

he turned to his human form, extending his hands to you in a pleading gesture, begging for you to not scream, you had already seen him in his natural form and he had no time to turn invisible, you then sprint off as fast as you possibly could, reptiles eyes widen

"Sh*t!-.. human!--"

he stays there shocked for 2 seconds then runs after you, he pants but reptile continues running after the man
