Samuel's ears perked up as Charles started talking. If it was unofficial business and Charles was confiding in Samuel of all people, he wanted to make sure he had his full attention. Charles may be a good friend but he wasn't exactly the friend you took down to the strip club to have a nice look around.
He took a sip from his drink as he listened to Charles and choked a little as he said that Kathryn was back. Coughing a few times, Samuel looked at Charles with wide eyes. "Is she really now? What brought her back?" Samuel was well aware of the history between Charles and Kathryn, having been there when it was all happening and watching her get escorted off the island.
"Of course, anything you need. Have you told Emily and Evan yet?" He hoped that Charles had at least told Emily but he knew that he probably hadn't. And it was probably for the same reasons that Grace didn't know she was actually Samuel's daughter but adopted by Danielle. Some things were better left under the rug for the time being.
