Cuz this is the first time either of them has confessed out of choice.

Let’s look back- before Mama Star, Star and Marco had three confessions they didn’t want to have:

One in Starcrushed

On in Booth Buddies

And one in Curse of the Blood Moon

There was also this one in Curse of the Blood Moon that they actually chose to have

But it still didn’t feel right because they didn’t think they were allowed to be happy about it since (1) Star is still with Tom at this point and (2) they knew it was about to be erased anyway.

But THIS?

This is the first time Marco’s been able to be honest about his feelings for Star out of choice. He has a moment where he’s wrestling with what he wants and then decides all he really wants is to be with Star so he lets himself confess. And it’s so great because this time he actually WANTS to.

And the other thing that makes it great?

Star’s allowed to be happy about it. She heard what he said, and even though she knows he forgets that he said it and she’s about to lose her memories too, for the first time she knows she doesn’t have to be scared about what they have. She knows she doesn’t have to run from her feelings anymore because he’s not running from his. She knows that, when all the craziness is over, they’ll finally be able to be together because they’ve decided to be.

It ties together their fate vs free will narrative really beautifully. Every other confession has been something they felt like they HAD to do. This one is one they WANT to do. And now is the perfect time for it because the past few episodes have been full of moments of characters thinking about what they want for the future. And even though Star and Marco haven’t got it all figured out, they do know that they want to be with each other through it all.
