Yes, both of these are canon.

Chainstopper : You guys smash for a robot?

Ove: What?! Why would I crush Astra?!

(He doesn't know what he means)

Chainstopper : You don’t understand, kid.

Heh dab me up, im in

SHE'S 3 YEARS OLD

when did i start to care?

Pedophile

Ove: It's not my fault that I... Mmph!
*gets flustered and angry at the same time*

Astra: hunter is just a creep. I barely know him, and who the heck just straight up says "you're hot" when meeting someone!?

*Deep breath*

Sorry. Got a little mad there.

Ove: I mean, you can stay if you want, but...
*He hugs her really tight, and Astra feels a few tears drop on her shoulder*

Astra: ...

I guess I can stay.

Wanna go prank your sister for eavesdropping?
(That means spying on people in case you don't know.)

Ove: I... I know what eavesdropping means.
Sure... If that's what you wanna do.

(it's just a word I don't hear often)

I kinda feel like it would about right there for comedic effect

Huh

I was thinking about making this into a short comic

Maybe it's mostly text but still

Hmmm

Ove: Thank you... *Cough* Astra...

*The crack heals mostly, but there's still a small crack in spot of the large one*

*Astra picks him up and carries him back home*

Ove leans against her and lightly smiles all the way there, and they arrive.

*Omi is freaking out after hearing what happened while eggy looks for some bandages*

Eggy: I th-think I remember, y-you have some instant h-healing medicine, right?

Omi:
*stops panicking and thinks for a sec*

Oh yeah.
*She grabs the medicine, applies it to the injuries, and he heals in a few seconds*

Ove: *wakes up* M-mom..? Dad?
*Rubs his eyes and sees Astra holding him* A-astra!? *He blushes a bit*

Astra: you passed out about halfway back here, I was kinda worried you wouldn't wake up.

Ove: That was... Very brave of you Astra... Thanks a ton.
*He's still blushing, and feels embarrassed about what happened and what he did*

Eggy and Omi: We were so worried!
*The two of them pull Ove and Astra into a group hug*

Astra: *hugs ove*

It's really sweet that you have feelings for me, but... I'm just not sure how this would work.

No matter what way you look at it this is gonna look weird, it's either a 16 year old in love with a 12 year old, or an 8 year old (I think that's what you said) in love with a 3 year old.

*Stops hugging him*

So, how about we just stay friends. At least for now.

Ove: oh...
Okay...
*He looks down, a little sad, but was honestly expecting this*
I...
...
So...
Do you have to go home now?

Astra: well if it's awkward for you now because of... All of this, I guess I can.

Yes, they're from gravity falls.

Why do I suddenly imagine ove and essy are like dipper and Mabel

...WAIT

I JUST REALIZED SOMETHING

Aren't those the guys from gravity falls

Astra: go on...

Ove: like I said... I'm not gonna apologize for what I did... Because I really do have feelings for you... I really want to be with you, y'know?

(you know what I mean)

Astra: how long have you been standing there?

Ove turns around to see her

Essy: long enough to hear all that, hehehe... *Runs away*

Ove: *sigh*
I love Essy, but she gets on my nerves sometimes... But as I was saying...

So ove is apologizing but also watching with a bucket of popcorn?

Oops meant to say Essy

Astra: (whispering to ove) we can keep what happened before you fell a secret.

Ove: ... Thanks.

After a couple minutes, Eggy and Omi let go of the two of them and go to their room.

Ove: I... I'm not gonna apologize for what I did. Because I really do like you, and... I wanna be with ya. They say somebody my age doesn't know much about love, but... They're wrong.

Meanwhile, Essy watches with a bucket of popcorn.

Ove: He did what?!
That crazy idiot... *He can't muster up the courage to say anything else*

Astra: right? And trollface got an earful from the Collector after that since hunter is one of his goons.

*She notices ove is hesitating to speak*

It's ok to talk, I honestly think it's sweet you have a crush on me even if I'm not sure it'll work out.

Ove: ...
*He tries to look away as a tear slides down his face* I...
...
*He leans over and kisses her on the cheek, before running away as fast as he can*

Astra: Well... That just happened...

(so... Is canon? Ye of ne?)

Ove hides behind a large tree, but Astra sees him jumping behind the tree...

(I'll think about it)

Astra: (to self) maybe I should leave him alone for a bit. He really needs to work on his hiding though.

There's a massive CRACK! As ground
under the tree breaks, and the tree, along with Ove, start careening over and down a cliff...

Ove: AAAAAAAaaaaasttttrrra...

(You know what I mean)

Well going slow won't help him

Astra: well would you look at that, a plot twist.

*Astra activates her doc ock arms and begins slowly climbing down the hole*

(hole? He's falling down a cliff)

(since he's eggy's son he'd probably be able to survive the fall.)

Astra: (about halfway down) well there's the tree but where the heck did ove go?

Ove is lying on the ground with a huge crack on his head, yolk is spilling out of him, and he's crying loudly...

Astra's eyes widen as she jumps down from the side of the cliff

Astra: it's gonna be ok! I'll get you home and we'll have you all fixed up!

She sprays a strange substance on the crack and yolk stops spilling out

Astra: also I may or may not have heard that from your sister.

Ove: *is too sad to care*
