Do you have any idea what time it is?

Tom sat up in his bed and stretched lazily. "Guess your curfew idea didn't work as well as you thought, huh, Chakotay?" He felt a smug smile spread over his face as he hopped out of bed and started dressing quickly.

My...what?

Chakotay's voice sounded genuinely confused, which pulled Tom up short. He gave his comm badge a funny look. "You know, the cur- You know what? Never mind, I'm on my way. Paris out." Tom shook his head and finished pulling on his uniform. Chakotay had been pretty self-satisfied last night; it was weird that he'd act like he didn't know what was up. Maybe he'd acted without Janeway's consent and didn't want her to know. "Too bad," he muttered.

Tom assumed his post on the bridge, ignoring Chakotay's look. He'd meet with Captain Janeway and talk to her about her first officer just as soon as he went off duty later today. Harry called over, "Tom, we've been doing some scans on a star we're passing. I'm sending you the telemetry now."

Paris nodded acknowledgment back at his best friend and looked down at his console. To his surprise, it showed a binary star. He checked over the readings twice before speaking up. "Harry, is this a joke?"

"What?" Kim looked at him askance. "No."

"We've done this."

Harry shook his head slowly. "No, we haven't."

"Yes, we have. We scanned and catalogued this star yesterday."

"Tom, we've never been through here before."

"Perhaps you are experiencing a paradoxical state-dependent associative phenomenon," offered Tuvok helpfully.

Tom looked back down at his panel and shook his head in denial. "No, I'm serious, we've physically been here and done this. This star, it was the first one we scanned yesterday. Same coordinates, same readings, it's the exact same star!"

Janeway came over to stand behind him and checked over the readings. "You're sure, Tom?"

"Yes!" Paris said. "Positive."

"Then why isn't it in the database?" Harry asked. Everyone turned to look at him and he tapped his board. "I just looked. No such record."

"But..." Tom's face fell. The captain smiled at him kindly, but he could tell she didn't believe him.

"Sorry, Tom, but it looks like Harry's right. We've never been here."

Paris felt entirely confused, but accepted that he could have had some kind of weird premonition. He was just starting to believe that he'd been wrong when Harry commented on a brown dwarf nearby that looked like it merited scanning. Tom turned in his seat to stare at him again.

"At coordinates 227 mark 159?" Kim checked his console, then looked up at him.

"Yeah."

Tom slapped his console in triumph. "I knew it! We have been here before! That's the second of the three stars we catalogued yesterday." The entire bridge was staring as he went on. "The third one was a red giant that Tuvok thought would go nova in the next decade or so."

All eyes went to Tuvok, who calmly did a scan before reporting: "There is such a star in the immediate area."

Janeway stepped back over to Tom. "What else did we do yesterday, Lieutenant?" Tom thought about it.

"There was a nebula. A really big nebula in the same system as the brown dwarf that you thought looked interesting. But we couldn't explore it because the gasses and radiation inside would melt the duranium off our hull." Janeway looked up to Harry, who confirmed everything Paris had said.

"But we haven't been through this sector of space before, Captain, I'm sure of it," added the young ensign.

"Recalibrate the sensor array, check for malfunctions." The captain turned and fixed Tom with a curious stare. "Meanwhile, Mr. Paris, I think you'd better get down to sickbay."

The Doctor ran the medical tricorder over and around Tom's body while the pilot fidgeted impatiently. Janeway and Chakotay looked on in silence. Finally the hologram closed the tricorder and reported, "Mr. Paris is in excellent health. There's no evidence of delusions of any kind, and physically he's fit as a fiddle."

"So he's telling the truth," the captain said slowly. "He really did live through this day already."

The Doctor nodded brightly. "That would seem to be the case. And I think I might even have the why."

Janeway cocked her head to the side. "Explain."

The Doctor beckoned her over. "Remember the accident Mr. Paris got himself into a few days ago?" He showed her Tom's scans.

The captain snapped her fingers. "Of course! The chroniton radiation!" She gazed at Tom as if she could see the residual radiation on him. "The chronitons did something to make him move forward in time by one day."

"We could scan for subspace anomalies, anything that would trigger that kind of reaction," Chakotay suggested. At Janeway's nod, the first officer tapped his comm badge and spoke quietly to the bridge.

Kes approached Tom and looked at him closely. The helmsman said, "You know, you did that yesterday. Looked at me like that. You said you got a weird feeling."

"I'm getting a weird feeling now," admitted Kes. "It must have something to do with the time displacement. The way you were thrown forward one day." She smiled at him. "It must be strange, living the same day over again."

"Yeah," Tom sighed. "Just a little."

Paris was allowed to remain off-duty, so he wandered down to the hangar to re-fiddle with the Earhart's navigational controls. But to his surprise the controls were exactly as he'd left them yesterday. He got a hunch and scanned around with a tricorder. Sure enough, the aeroshuttle still held residual chronitons. "So you must've been thrown too," Tom murmured to the ship, patting the bulkhead fondly.

Tom met Harry for pool at Sandrine's and, predictably, beat him again. "You know, it's not fair," said Harry. "If you know what's going to happen, then you have an unfair advantage."

"I have an unfair advantage any time I play you," Tom replied cheekily. The doors breezed open behind them and Paris called, "Tuvok! B'Elanna! Come here and grab a cue, play a few games with us." The two aliens wandered over with bemused looks.

"How did you know-" B'Elanna started, then caught Harry's eye. The ensign twirled a finger around his ear, indicating that Paris was cuckoo. Torres nodded and snatched up a cue. "You're on, Paris."

The four of them played a championship. Tom did his best to not play as he had yesterday and the games did come out a little differently. But still it was Tuvok that faced down Tom Paris at the last game for the win. The Vulcan opened his mouth to call his shot, but Tom held up a hand.

"Tuvok, just do it." The security chief raised an eyebrow, but did as he was told. Tom caught Harry's eye and mutely pointed out the path the ball would travel. Kim had just started laughing at Paris' prediction when Tuvok's ball followed Tom's track precisely. Harry's mouth hung open as Tom and Tuvok said in unison:

"I believe this makes me the champion, Mister Paris." Tom rolled his eyes and laughed ruefully. "Yeah, yeah it does."

Tom Paris stayed late at Sandrine's; partly to redeem himself by soundly beating Tuvok at two consecutive games of pool and partly because he didn't want to have to read Chakotay's curfew note when he got back to his quarters. When he finally did head back, the note was there waiting for him.

He took one look at the padd, then deleted the message without looking at it and threw the padd onto the couch. Then Tom realized he'd forgotten to talk to the captain about the curfew. It'd completely slipped his mind, what with it being deja vu day and all.

Tom got into bed with a weary sigh and huddled under the covers sleepily. He'd talk to Captain Janeway tomorrow, when he had a fresh day to work with instead of the same one he'd already been through once. He fell asleep thinking about just what he'd have to say to her about her arrogant first officer.

Chakotay to Paris.

"WHAT?!"
