Do you think Star is aware of her feelings?
I’m going to use this picture that @seddm used to answer a similar question.
I think Star is more intrigued than aware. Her uncharacteristically quiet tone used to deliver “it’s just the two of us then?” in “Camping Trip” is tinged with interest. I feel like she doesn’t exactly know how she feels; maybe she thinks she likes him one day, then writes it off as her just being dumb. She just cares about him because they’re friends, right? Right?
On the other hand, though-
Star has been shown to run from her problems, like confrontation with her mother, for instance. While that recently got some resolution, (which I would like to revisit sometime, actually), she has still been known to not want to deal with things. She sees her feelings for Marco as a problem; a problem she doesn’t have to deal with. She can hug him, hold his hand, and so on… all platonic in its nature, supposedly. Why would she need anything else? She just buries it and ignores it. However, now that Jackie is in the picture, I believe Star’s about to have to actually face a problem head on…. or risk breaking her own heart.
