So I mentionned that Naeva speaks spanish but I didn't mention it was her mother language... So Naeva's first language is not English. So here are exemples of Spanish Naeva :)

~~~~~

When Naeva is so tired that she can't speak english anymore because it's too hard for her brain at this point:

Naeva: Oh mierda, estoy cansada...
(= Oh shit, I'm tired...)
Scout: Did Naeva became mexican out of sudden?
Soldier: Did Naeva became like Pyro so we don't understand them anymore?
Demo: Is Naeva drunk?
Naeva: Oh, honestamente, que se jodan todos en este punto. Solo quiero dormir.
(=Oh, honestly, fuck everyone at this point. I just want to sleep.)
The Red team: ???
Naeva: *incoherent Spanish mumble, then proceeds to fall asleep on a chair.*

~~~~~

Naeva giving spanish nicknames to the team or Pauling to make it cute <3
And also her talking to Pauling in Spanish:

Scout: Yo Nae, wanna eat chicken?
Naeva: Hell yeah, hermano.
(=Hermano means brother)

•••

Spy: Where is our idiot?
Naeva: I'm here, pa.
Spy: Ok- wait what.
Naeva: I said 'pa'.
Spy: ...
(Pa is a way to call your dad)

•••

Naeva: Oh, mi corazòn, you kept my jacket?
(Mi corazòn means 'my heart')
Pauling: Well, yeah.
Naeva: Ayy, que linda~
(= Ayy, how cute~)
Pauling: *blushing furiously*

~~~~~

Naeva singing in Spanish and telling about her favorite song:

Naeva and Scout talking:

Scout: My favorite song is 'Sex bomb'.
Naeva: Nice. My favorite song is 'Me gustas tú'.
Scout, who don't speak a word of spanish: ...What?
Naeva: *sighs* 'I like you'.
Scout: Oh, I like you too, sis.
*Naeva.exe has stopped working*

•••

Naeva: *humming* Me gustas los aviones, me gustas tú *looks at Pauling*
Naeva: Me gustas viajar, me gustas tú *looks at Scout*
Naeva: Me gustas la mañana, me gustas tú *looks at Spy*
Naeva: Me gusta el viento, me gustas tú *looks at Pyro*
Naeva: Me gusta soñar, me gustas tú!
Me gusta la mar, me gustas tú! *looks at the whole team*
The team: *have no idea what she's saying but enjoy her silly humming anyway*

(Basically, translation of the song:
I like airplanes, I like you
I like to travel, I like you
I like the morning, I like you
I like the wind, I like you
I like to dream, I like you
I like the sea, I like you)

~~~~~

Naeva cursing in Spanish:

Naeva: *takes a hit* ...HIJO DE PUTA!
(=SON OF A BITCH!)

•••

Naeva: So... Who critically hit Sniper?
Medic: The Blu Spy.
Naeva: ...Qué cabrón!
(=What a bastard!)

•••

Naeva: *drops something* Puta madre!
(=Motherfucker!)

~~~~~

Naeva having a spanish accent at first, but as time goes by, her accent vanishes.

Naeva trying to teach Spanish to the team because she sometimes miss her mother language but genuinely fails.
