Bob invites Connor to dinner, but he gets an uneasy feeling about it. Bob thinks he has good sense of humor, but he's too sharp to be taken kindly.

When Bob, Connor, and Linda are alone sharing a drink, Bob launches into Mick's business. They're so insensitive and how they talk down to Connor shows they're not the firm that Connor should be working for.

Mick and Thomas are going to hike the Appalachian Trail. It's an adventure. David and Jess arrive with beef stew and wild mushrooms. Apparently, the inn is full since people are looking for the Snallygaster, a mythical creature that is half bird and half octopus. David is like, huh?

Kevin is concerned about Cap. Sarah said his former partner was named Carl, and he died in a fire.

Megan takes food to Driscoll, but he still shuts the door in her face. Twice.

Thomas is obsessed with how slow they're moving. Then they begin talking about the competition between them and how Thomas thinks Mick was his favorite. Then two young men bypass them on the trail. They don't know how to pace themselve. They'll burn themselves out.

How about that plus one, Abby? Jess suggests Jay. They're something going on there, and it might be just what Abby needs.

Abby and Connor have a lot of digging to do for that file.

I bet they're going to find something helpful for the case.

Yep, Abby found contracts from when Dilphor was on staff. There is a signature on the original document, but Mick was in Florida for Connor's favorite birthday. He took them to DisneyWorld. They subequently find a photo with a date of the family, which means that Dilphor forged the document. And if he did one, there could be more.

A dude named Mr. Sullivan visits Luke at the bar. He's Luke's Probation Officer. He just wanted to come by in person to his new place of employment.
