Rose Lalonde has many facets to her character. None of these include good relationship skills.

DAVE: sorry man i dont think nepetas the type to purposefully doctor text messages to show her romantic endeavours

ROSE: I am just saying, you can never be too confident.

DAVE: dude is this the reason that you and kanaya didnt get together until vriska literally-

ROSE: Unnecessary Vriska mediation aside, Kanaya’s courtship was rather straightforward, and given the fact that her and Nepeta have been close since they were 5 sweeps, I’d say it’s rather probable that she’d attempt to copy some of her moves.

ROSE: Especially since our love life is the most successful out of the whole meteor.

Shitty technicalities are a part of her facets, so you have to let that slide. You guess.

DAVE: ok shitty technicalities aside: that just doesnt seem like a nepeta thing yknow

DAVE: maybe shed like something real corny

DAVE: id need to alchemize a cd player and shit but maybe shed be into that

Rose looks at you, and you can tell that you fucked up.

ROSE: Oh? I thought we were discussing whether or not she was into you, not the other way around.

ROSE: Was this a ruse in order to figure out if Nepeta shared your attraction?

GOD DAMMIT.

DAVE: well

DAVE: shutting the fuck up over that for a second

DAVE: the possibility of that being a thing

DAVE: is a thing that could be true

DAVE: doesnt even fucking matter when you remember that she might not even be into it

DAVE: because if she isnt than im not

ROSE: Obviously.

DAVE: obviously

ROSE: And we can't just ask her.

DAVE: obviously

ROSE: Obviously.

ROSE: Maybe we could manufacture a wild teenage party, which could leave Nepeta in an inebriated state, and therefore more willing to share any sort of feelings she may have.

DAVE: no dude your just saying that because your cold turkey

You lightly slap her on the shoulder, and she gives you a weak glare. It's a Lalonde glare, so it's still bad, but you know she could do better.

DAVE: fuck man...

DAVE: maybe i SHOULD be looking into our pesterlogs for subliminal shit

ROSE: Atta boy, Dave.

DAVE: you think neps getting advice like this?

ROSE: Maybe, but yours is no doubt better.

ROSE: After all... this is Karkat's advice we're talking about.

The two of you laugh at that, and you realise you pretty have have this whole scenario in the bag.

Nepeta's gonna have all her feelings out in the open, she has NO idea.

You hope.
