Simon does not expect physical retaliation. Not from some guy with silver hair. He's rather shocked when he suddenly finds his arm grasped - and painfully, too - his eyes widen, and he clutches Estelle very tightly with his other arm, trying to pull away. "Let go! What are you doing? That hurts!" he snaps, not yet making a scene about it, but on the verge to start really shouting and struggling. He eyes Milo's swishing tail with some apprehension. "I don't know! A few hours! God!" It's not even like it's permanent! "Stop manhandling me, or I will kick you." Except he can't, because he's holding Estelle, and he can't risk damaging her by getting involved in a physical altercation. "You did this to yourself - you tried to make Daisuke hate me, so now you have a tail. You're an adult, so act like one and deal with it!"
