I think it’s some combination. She’s not sure how things will turn out, is very nervous, but is also glad the truth is coming out, but mostly that looks like a nervous grin, kinda like the nervous grin Pinkie made in “The One Where Pinkie Pie Knows”.
 

 
It’s got the stressful creases at the corners, the gums visible in the sides, and the upper and lower teeth being slightly mis-aligned, and the slight raise at the bottom of the eyes, so it’s a stress smile.
 
So, basically, a Twilight’s not a jerk.

Moments like these really makes me hate Twilght. Being “right” isn’t all that important. Maybe that’s why the map is so reluctant to send her anywhere.

Twi’s expressions are soooo golden.

sigh, another photo lost to the merging process.

It’s more like failed pokerface, than a sociopath’s smile

Do you have a problem with that, nigga?

Twilight’s face is pure gold… i smell memes incoming.

Looks like a nervous “I’m not sure how this will turn out” smile to me.

RD: “That’s it; we’re doomed.”  
TS: “Yeah, isn’t it great?!?!”

@FilthyRichFan25  
She wanted to tell the guy the truth from the start, so when Vapor came out and said it she thought it was a good thing. She even keeps smiling for a while till things really start going bad.

why is twilight smiling like that?

If I was at my computer, I would immediately put those two expressions together in one image and it’d be wonderful.
 
But for now, I’ll simply say this means he is a ghost or zombie.
 
…Seriously, though, don’t say “literally” if it’s not literal, otherwise you’re just damaging the English language because the word “literal” is needed with its real meaning.

I literally died laughing at this.

This screencap is way funnier when animated, and it was pretty great to begin with XD
