Since everyone else was in beach wear (likely, whether they liked it or not), Jonas had gone with the flow and changed up his "clothing".

Cassie, your boyfriend has spotted you from down the beach and is approaching, wearing a tiny square-cut swimsuit in dark green.

Said swimsuit also had the word [CENSORED] written across the back. Not that Cassie could see this. Or anyone else for that matter, because Jonas was still wearing his cape.

"[Over here, Cassie!]"
