Sam finally stole his gaze away from the closed door, and smiled tightly at Stacey.
"Sure thing," he muttered, trying to get his mind off Ethan possibly trying to steal Stacey back. It wouldn't work, anyway ... or at least, I don't think so. He knew he loved Stacey, and he also knew that she loved him; but Ethan had once been special to her, and he hoped that Ethan's presence wouldn't remind her of the past.
"Sorry, babe," he said, smiling in a more genuine manner this time. "It's not your fault," he added.
