"Hey sleepyhead, we're home," Peter nudged Olivia awake.

Astrid put the car in park on the street next to the Bishops' new-found home.

"If you don't mind, Peter, I'll take the car back to the lab tonight and then I'll pick up Walter tomorrow morning," Astrid said.

"Sure, no problem. Thanks for all your help, Astrid."

Olivia rose from her position from the backseat off of Peter's lap, a bit groggy and unsure of how long she'd been out. As soon as she sat up, she groaned as she stretched out her back.

Walter opened her car door and said, "I hope you're hungry, Agent Dunham. I'm going to make the best potato soup you've ever had!" He held out his hands and she took them so he could help her out of the car. Peter followed closely behind her, keeping a hand on her back to guide her.

"That sounds surprisingly nice, Walter," Olivia managed to say as the world took a spin when she stood up. She swayed a bit but Peter was right there to steady her.

"Whoa, you gonna be okay to walk?" Peter asked.

"I'm good," Olivia nodded and smiled weakly.

Walter got the bags out of the back of the station wagon and said goodbye to Astrid while Peter walked Olivia up to the house.

"Potato soup?" Olivia looked at Peter skeptically.

"Actually, it is pretty good," Peter said as he jiggled his key in the door knob. "It was my mom's recipe. She used to make it for me when I was sick."

"Oh," Olivia replied. "You know, I haven't seen your new place yet." Peter opened the door and let Olivia enter first while he grabbed the light switch. "It's nice."

"We like it. We're glad Broyles was able to make a deal for us."

"Well, it helps to know the right people," Olivia looked at Peter and smiled.

"That it does," Peter smiled back. "Make yourself at home, Olivia. How are you feeling? You should sit...or lie down. You can take my bed upstairs," Peter suggested.

Olivia headed for the couch and sat down. "I'm not taking your bed, Peter," she protested.

"Seriously, I'm sleeping on the couch tonight. You're forgetting that's how I've slept this whole time since before moving here."

Walter entered the house and put their bags on the floor. He was wearing the hat that he found along the riverbank.

"Nice hat, Walter," Olivia chided. It was too small for his head and he looked ridiculous in it.

"Hat?" Walter was confused. Olivia pointed at his head.

"Oh, this hat!" he said as he removed the hat that he already forgot he was wearing. "I found this right where we rescued you today."

"Really? Let me see it," Olivia said as she eyed the hat more carefully. Walter handed it to her. "I've seen this hat before..." Olivia said, dumbfounded.

"That's funny, I said the same thing when I found it!" Walter chuckled. "But I don't remember where I've seen it. I've been wracking my brain but I just can't remember."

"The Observer," Olivia said slowly as she looked up at Peter in disbelief.

"What?" Peter was fascinated. "Are you sure?"

"Yes. I've studied all the photos numerous times over. This is his hat."

"Oh good heavens. Yes of course! You're right my dear!" Walter cried. "Oh I'm so glad you figured it out! That was driving me insane!"

Peter gazed wearingly at his father at the mention of the word 'insane'.

"What would the Observer's hat be doing at the very spot where I was found in the river?" Olivia asked.

"I think the better question is...what was the Observer doing there? If he left behind his hat, he was obviously there," Peter stated.

"Watching me fall to my death?" Olivia asked in amazement.

"Or trying to save you," Walter said seriously, his eyes looking far off in a daze. Peter knew that look; Walter knew something more but was afraid to tell them.

"Well, I best get the soup started!" Walter broke out of his daze and headed toward the kitchen.
