His little brother isn’t really buying the story. Later, Jack popped by Emily’s place to pick up Sammy and ask about Amanda because he hasn’t heard from her since that night on the beach. Nolan’s surveillance footage let Emily know that Amanda showed up at his boat and the engine trouble story was a lie. 

He sought answers from Nolan, who suggested he ditch the receipt and forget about it and Amanda. Nolan let Emily know that about the money receipt. She knew Jack was in this thing even deeper than he was before. 

The youngest Porter vowed to protect his brother the best he could. He was going to have a hard time with that after Benjamin Brooks started questioning Jack though.
