Eiro waited for the Guild receptionist to bring the right form over to him, while trying his best to avoid pulling any sort of attention toward him. He was more than just positive that Krog and Jess saw him, as they were also whispering to each other about Eiro, trying to figure out if he really was who they thought he was.
While Eiro's clothes as well as his mask were completely different to what they saw him in before, they did see Lugo before as well, and he barely changed. Although, now that Eiro looked at him... It seemed like Lugo got a little fatter despite the fact they've been on the move for so long. Maybe the diet wouldn't actually be that much of a punishment after all... it would most likely end up helping him, after all.
