Throughout the many loops certain things had changed. Unsaid words and thoughts had become real.

Slowly Lines were drawn in the sands of countless repeats, things they just couldn't do, couldn't bring themselves to even attempt.

For example, Rue would never try to Kill Katniss, wouldn't even hurt her if she could and it was something Katniss quietly agreed too. Having never so much as scratched the young girl in what must have been centuries at this point.

Peeta would never use poison, it could be in the middle of a loop with everyone trying to kill everyone else and yet if you stumbled upon a cake (Katniss Still had no idea how he did that without an oven.) in the middle of the forest the cake would be completely edible.

There might be traps around said cake but the cake itself would always be harmless.

Clove, she would kill you without a thought, wouldn't even hold a grudge about it in the following loop. However she would never make it painful, not anymore. She would always make sure another tribute wouldn't suffer.

However no one else would be given the same privilege.

At some point Thresh Stopped looting the bodies of anyone he killed. If you were alive stealing was fair game, but never if you were dead.

They never talked about, they never explained themselves, but they all knew it was these small things that helped them stay mildly sane.

Sometimes Lines were crossed, it was inevitable and sometimes it just wasn't possible to avoid it.

Rue had killed Katniss, only once and completely by accident. Yet Rue had been a shell of herself for nearly thirty loops, simply collapsing into herself and waiting to be killed every loop until Peeta, and surprisingly Cato had managed to snap her out of it.

Katniss found she had developed a fondness for nuclear explosions.

Mostly the pretty mushroom cloud, but that one loop she'd spent six months running around a freshly made wasteland had given her a taste for radiation grilled fish.

She still wasn't entirely sure where District Thirteen was hiding, but she had gotten really good at making them show up out of nowhere.

Mostly it just took pissing off Snow, but on occasion she'd managed by annoying other politicians, which was very confusing since most of them wanted to genocide the twelve districts.

Strange Since almost every time thirteen showed up they instantly tried to rally the other districts into rebellion.

Admittedly Katniss only really cared since they kept either recruiting Prim, or killing Prim by 'accident'.

She found herself shrugging to herself as she leaned against Peeta on a burnt out log, as he fiddled with his primitive oven. Well she called it an oven but it was more like a rock box lined with metal using the background radiation to heat it up.

It was getting pretty hard to keep her eyes open, and her skin was tingling in a way that she knew meant she was approaching acute radiation sickness.

All Katniss could think about as her vision went dark, was that she wasn't going to be able to eat Peeta's newest cake. A sad thing really, as she was looking forward to uranium enriched strawberry cake.

At this point they had all mastered their own bits of weirdness, Peeta could disappear in an empty room, Clove had learned how to make knives explode in more than just icy balls of fire, Cato could apparently fuck with time somehow. Not that even he understood how it worked and it only seemed to happen when he had a sword. Still that time he'd stood in front of fifty peacekeepers with armed with armor piercing rounds and walked away with a single scratch on his cheek was just showing off.
Katniss had even learned how to set herself on fire without self combusting.
Admittedly it was a bit of a work in progress and she still died a third of the time, but bursting into flame while Snow ranted at her for ruining things would never not been funny. The man pissed himself half the time, and would scream bloody murder the rest.
Well on the occasions he didn't just pass out.
It was even funnier when she did right in the middle of District 13, According to Peeta they spent the rest of that loop looking for bio weapons and didn't even manage to Nuke the capital like they'd planned. Not that it would have worked since Peeta had long since stolen the uranium right out of the Nuclear missile and replaced it with some snicker-doodle cookie dough.
Though everyone said the Uranium enriched strawberry cake he made wasn't very good.
Katniss still wanted to try it.

The loops were honestly just a given at this point, so much so that it was completely disorienting when she found herself waking up in front of the train station, dressed in her tribute dress as she looked around in confusion.
It was only glancing to the side and seeing Peter's eyes just as confused as her own that kept her from going- er well something? She wasn't actually sure what she'd do if she fell into a panic at this point, and Katniss didn't want to find out.

Either way as she was shuffled off into the train by the announcer, she had a feeling things were just going to get weird.
Something that was proven when she entered the train car only to find Haymitch looking both worryingly sober and at Katniss and Peter like they were ghosts.
