Ok, we already know these informations from the previous livestream:
-She already said that she's given up on her real name in the previous live, so no point in asking that
-she's read some parts of star's diary but she'll never reveal what's written inside
-we already know how she met Star (casually at school, from that moment she knew she would to obsess over her)
-apparently she was given a laser puppy, if that's still legit (it appeared twice during her previous live)
-Star gave her the lamp on her desk, if I remember well.
-"starco? I have no idea what that is. Do you mean Marar?" Also she didn't think star loved marco, because Star definitely loved her and she loved Star. Definitely.
-she doesn't SPY on Star, she only constantly watches what she's doing
-ok to cut short, she's definitely a raging lesbian for Star
We could ask:
-what did she do in her life before Star came to earth
-whom she'd ship Star with if she couldn't choose herself
-why did the chicken cross the road (to reach you on the other side, you homo)
-what does she think of [character]
-since she's said that she likes everything Star likes, would she like Marco too if Star openly did?
-if she did any fanart of Star
-how the laser puppy is doing
I can't think of anything else.
