Riker tried several times to stun her and it wasn't effective. He finally used the highest setting in order to stop her. Presumably he'd already attempted to use all of the lower, non-lethal settings.– The preceding unsigned comment was added by 22.214.171.124 (talk).
a: seems like a cop out. Even if there the phaser stun did not stop her with one shot -- Riker already knew that the Yuta-virus would pose no danger to anyone else. Riker could have beamed over with Worf if he thought he couldn't handle her. Riker did not try to physically restrain her. Some may think was Riker putting her out of her 100 year single-minded misery. I think Riker is a cold-blooded killer because Yuta said he could not please her? %^) Twitter.com/TercoTalko– The preceding unsigned comment was added by 126.96.36.199 (talk).
