Summary
Analysis
Callum wasn’t sure if Sephy was going to show for their trip to Celebration Park. He’s never sure if she’ll show up, though. But Sephy did show up—she crept up behind Callum at the station and dug her fingers into his kidneys to make him jump. When he asked her not to do that, she said he loved it and sarcastically said he was in “one of [his] sunshine moods.”
Callum doesn’t seem like he’s secure in his friendship with Sephy if he never trusts her to show up. This could be because of the power difference between them: as a Cross, Sephy has way more power than Callum does. And making Callum jump like this is one way that Sephy lords that power over Callum, though it doesn’t seem like she realizes she’s hurting him.
