They were sent after a Cursed Spirit, but when they got there, you were fighting the Cursed Spirit and didn't seem to need any help

Gojo: Huh? Interesting. He was excited and stood there with his arms crossed as he watched you fight

Itadori: What? Were they supposed to be here?

Nobara: I don't think so, but at least it's less work. She smiled as she watched you fight.

Megumi, Panda, Toge, Maki and Nanami: They just watched you fight, ready to help if you needed help.
