Here's the revised version with corrected grammar and improved clarity:
Orion followed Erza and took a seat beside her. Victor and Mark sat next to them on Erza's side.
On the other side, Tracy sat beside him, followed by Henry from the Black Reaper Guild.
Leonard and Drake from the Druid Guild sat opposite them, followed by Louis and Cicile from the Catalose Guild.
"I don't see the two from the Hunter Association," Orion said, observing everyone around him.
"Who? George and Nolan?" Victor asked.
"Yeah, them," Orion nodded.
Victor shrugged. "If they're not with us, it means they're in another part of the shuttle, or they might have left before us."
"By the way..." Orion was about to ask something when he noticed Mark staring at him and Tracy with a sour expression. He understood that look well — it was one of helplessness, self-directed anger, and frustration at his own abilities.
