Not exactly. Even when you're playing for the first time, reading his and Flowey's dialogue seem to imply they do have an inkling that this has happened before. I would assume it's due to the game limitations - it's impossible for a programmer to account for everything.

But Frisk can have eliminated all monsters in the cave, if Toriel was spared, the run becomes neutral. Likewhise, Frisk can kill everything but one froggit, then leave the ruins bathed on Toriel's dust. He still won't be hostile.

Yes, I agree with the sprite thing, but he actually points out Frisk's stoic at that point in time, several times, and that he finds that freaky.

He's too precise in what he tells you for him to merely have impressions. Toriel, Papyrus, Undyne, none of them are ever that precise, they talk about 'feelings'.

When you're fighting Sans, he's pretty stressed out. Considering how there are bones all over the place when he attacks you, he probably wouldn't have noticed if you died or just left. Flowey wants to outright screw with your mind, so he nitpicks. Sans only wants you to quit.

You can't quantify how many times a person has died by looking at their face. The first time, it would be plausible - you would see shock. The second time, frustration, maybe still some surprise. From the third onwards, you would only ever see the same expression, until it escalated towards rage. You can't simply say "Ah, you're just frustrated enough for this to be your fifth time". It doesn't actually make any sense.

What makes more sense is that Sans is trolling you. It would fit his personality.

Have you ever noticed that almost always when he aludes to resets, he talks about Frisk's expression? He never gets "feelings" like the others. That's strangely convenient. In the beginning, when Papyrus feels like he knows you, Sans trolls him instead of being contemplative/agreeing, as if he didn't actually even have to consider the idea. (https://youtu.be/3Jn77RQg75c?t=13m26s)

The two times I notice he doesn't alude to expressions are the screenshots I sent earlier (after Papyrus death), and when you spare him in genocide and return (mid battle). Those times he acts like he's absolutely certain of what you did anyways. There are probably others I haven't seen/don't remember.

He also is clearly warning you about Flowey on your "first date". I doubt he would find it relevant to warn you about someone playing a prank on Papyrus. But he does so in a roundabout way, like he always does with the resets. (If you keep returning to Flowey in the end, you find out that Sans knew Flowey because he kept messing with Papyrus)

Also, you can reset just after killing Sans, before talking to Chara, without doing a true reset. He won't "read your expression".

He actually remarks on it in the end if you go through the game without ever saving (and thus, without ever resetting).

Either way... I feel kind of embarassed for derailing this thread so much. So, we should probably keep it to the original subject.
