In an obvious attempt not to roll her eyes out of her head at both of them for saying the most absolutely ridiculous things (Orlais will triumph, indeed), Adrasteia casts a look around the room to see if anything in the room has changed as Tony and Val bleed into their perspective portions of the blood collecting apparatus.

No matter what the result of her attempt to sense any shifting in the room she does join in the bloodletting, hopefully adding enough so that the bowl fills.

She doesn't want them to have to stand here for long, honestly.
