Ron was eating and talking to Harry during the evening meal when he heard the outburst from his daughter. If there was ever any doubt that Rose was a Weasley it would have been gone completely when Rose stood up on the table to announce her upcoming wedding. Ron pressed his face to his palm after the outburst and groaned. And then saw Hermione slap Rose when he lifted his face.
"Hey, come find me later I've gotta take care of this." Ron said without looking at Harry before he was up on his feet and moving across the room to where his wife and daughter were standing now.
"Both of you, can we do this somewhere else?" Ron knew himself well enough to know that he couldn't be trusted not to have some sort of equally loud outburst there in the middle of the great hall. And really Rose and Hermione had done more than enough of that on their own.
