"You can stop screaming now, or I might just toss you back in there," Grey said emotionlessly.

Without even looking at the contents, Ellis gulped it down. 

"Reckless, that was meant for… *Sigh* Forget it, it doesn't change anything," Grey looked at Ellis, hopelessly. 

How could he drink the contents of the bottle without even asking what it was or even inspecting it? Isn't he by any chance scared of being poisoned?
