While Belle didn't want her husband out of her sight period, she knew he'd go absolutely stir crazy if he didn't at least take a walk around their prison. Cooper couldn't stay indoors on a good day if his life depended on it. Something like this, no matter how much she wanted to cling to him, she knew better. He'd come back to her, he always did.
"I'll be just fine," she assured her, then returned his kiss. "You better, Cooper Bennett, or else I'll have to come lookin' for you first."
It didn't really occur to Belle that somebody might be watching them. They were pretty much stuck where they were, if the man was to be believed and this was a remote island. Miles and miles of ocean made pretty damned effective walls, especially with the threat of hurting somebody else if they tried to escape hanging over their heads.
"I love you," she murmured, leaning in for another kiss. "It's gonna be all right, isn't it?" Belle needed him to believe that as much as she needed to right now.
