Default Clutch issues.

So I did a bit of searching and couldn't find anything too similar to my issue.

My issue is the other night I was driving home, I stop at a stop sign, and when I went to put it in first I noticed the clutch pedal didn't come out as far as usual, but I was only a few streets away from mine and I thought it was just a fluke thing.

I get to the next stop sign(luckily a less traveled side street), put it in neutral while coasting to a stop, then when I went to put it in first I noticed the pedal was stuck all the way to the floor. I tried to put it in first but I couldn't get it into gear, and I had to manually pull the pedal back up, and got the car towed home.

I assumed it was the slave cylinder, or that it was just low on fluid. I checked the level the next day and there was in there, so I figured the was a leak somewhere as the car has 216,xxx miles. So I put fluid in the reservoir and have a friend push the pedal in and lift it back up a few times to see if I can find the leak, but there was no leak and the fluid level remained the same.

Now I'm totally stumped, does anyone have any idea what it could be, or have any directions they can point me in as far as what to look for to determine the issue? Thank you for any responses.

There are only 3 places it can leak- the master, slave and the hose that connects to the slave. Look inside the car above the pedals where the master cylinder pushrod comes through the firewall, if the master is leaking it will be wet with fluid there. Check under the rubber boot if you don't see anything externally.
Pull the intercooler to get a better look at the slave and hose.

Okay, will do.

I'm not sure what you are saying here.
You did, or did not, have low fluid?

How many miles on the clutch?
How low was the fluid level, if it was low?

You may have a failing/failed master cylinder

I'm assuming that was a typo and he meant to say there was none in there as he did say he put fluid in.
Also assuming that these are possibly original components, I'd say a leak anywhere in the system would call for replacement of everything- master, slave and hose. This would renew the entire hydraulic system in one shot.

Whoops, sorry, I did mean to say there was no fluid it when I checked.

There's about 70-80k miles on the clutch.

As far as in the engine bay goes, when my friend was pressing and depressing the clutch pedal there was nothing leaking, I checked in the bay and on the ground. The fluid wasn't going anywhere in the reservoir either.

Is it possible that the fluid just got so old and worn over the years and usage that it just got thin, weak, and essentially just evaporated?

It's a sealed system. Yes the fluid can get old and contaminated with water, air and bits of crud from inside the cylinders but it shouldn't leak out unless something is defective. Unless the hose bursts or a seal in one of the cylinders totally lets go, the leak can happen slowly over time and you may not see any fluid on the ground.
If you haven't already done so do as I suggested and pull back the boots on both cylinders to check for wetness, if you see any that's NG.
You haven't confirmed whether the cylinders and hose are original, if they are they certainly owe you nothing and it would not be a bad idea to just go ahead and replace it all.

I got the car with 93k miles, and I haven't changed the lines so I'm assuming they're original.

Thank you guys for your input

Okay so little update. After trying to bleed to clutch, my friend and I discovered a crack in the rubbed line that attaches to the slave cylinder. I ordered a new one at my local Subaru dealer and it should be coming in on Tuesday.

I will keep you guys updated after I get that in.

Yup I just replaced that line about a week ago, at a little over 130K. If yours lasted 216K that's pretty good.
It's not that hard to change but I suggest using flare wrenches on the fittings to avoid damaging them. Also try to change it quickly enough so the master doesn't empty out, makes bleeding it easier when you're done.
There is a spring clip that secures the hose to the coupler, once the metal line is loosened and removed that clip has to be removed (grab with pliers and pull straight up) to release the hose.
