This could all go very wrong. That was why Jack and Lien were here. He really didn't want to consider it as glorified babysitting but... if anything went wrong, Jack and Lien were here.

And also, maybe put the pressure on to get things right.
"You look lovely," Jack said with a grin looking at Lien beside him.
