[Back to the first day of vacation, in the POV of Walker and Gray]
Walker was completely exhausted to the point where Gray had to ask one of the flight attendants to get a wheelchair for him. Although Walker was fully clothed, one can still see certain red marks all around his neck and shoulders, but the person in question seemed unfazed, looking as though everything was normal.
The both of them arrived at one of the largest airports in Europe. After grabbing their baggage from the baggage claim and going through security, Gray contineud to push Walker, who was still on the wheelchair looking quite lazy, until the both of them arrived at the adjacent high-speed rail terminal.
Gray had actually no clue where they were going and simply followed Walker's instructions, so he could only grumble to himself as he looked suspiciously at the person sitting in front of him. Walker seemed to have noticed this and immediately turned around, giving Gray a rather mysterious smile.
