Seo Jun was watching Saphira closely as they get on the plane. Her eyes are wide with wonder as she had not been outside of HeJin's house since awakening.
"We have a 18 hr layover in London . Daisy booked us rooms at a hotel there.Jiro said he and Aria will meet us at the airport. " Wufan tells Shiro and Seo Jun as he takes his seat.
"Excuse me sir you have a tickets for four seats when there is only three of you. May I ask why?" The stewardess asks Wufan.
"I am not someone who likes to be close to others physically. So my wife always buys me an extra ticket. That way there is no chance of my having someone I don't know beside me." Wufan answers. In truth he wanted an extra seat for Saphira .
The fact that others cannot see her does not mean she needs to be made uncomfortable. Not knowing what effect her presence would make on others on the plane if they were to touch her by accident. Daisy suggested that they get her own seat to lessen the chances of a problem.
