It didn't take Yuna long to spot Rikku, and if for some reason she had missed her Selphie's running towards the group did draw Yuna's attention. Yuna followed behind Selphie in a jog. Then Yuna's ears caught the name Selphie had just spoke, and stopped cold.
Tidus?! Here? Suddenly Yuna became very concerned about her hair and how it looked. Tidus' attention wandered back to the moogle, Rikku and Claudia, only to move elsewhere when Selphie arrived on the scene. "Hey! Selphie!" He grinned at her. This was pretty lucky - he was running into his friends a lot sooner than he had expected he would. Now the only one left was Yuna. It was too bad Wakka wasn't here, too; he probably would have wanted to see all of them again after their unexpected departure from the Islands and not seeing them for so long, too.
"What's up?" Tidus asked. "Hey, isn't Yuna with you? I ran into Rikku and Claudia just after I got here, and Rikku said we'd go find you guys after finding Claudia's friends." He glanced around in hopes of spotting the missing girl.
He had to look twice when his gaze fell on someone who looked like Yuna, but... was not dressed like Yuna, standing only a short distance away behind Selphie. "... Yuna?" Tidus gaped, open-mouthed.
