Here's a good point. I plan to have this explanation in the story at a later
date, but for now...
Mike's allergy should have really kicked in when he got to the apartment.
If he started getting stuffed up just being in the car with John and Kasumi
on the way from the airport, being around Luna should really affect him.
This is a point of contention between my brother and myself, but I'll go
through the points.
One, the travel time from Tokyo International to Mamoru's apartment is about
20-30 minutes max... and the travel time from San Francisco International to
the Dwire house is 1:30 minimum... if the traffic's really good.
Two, Johnathon's half-cat form shed's a lot! Not only are we talking about a
cat as big as a man, but he wears clothing! Which means he's too warm, and
means he sheds even more.
Finally, Mike has been studying Tai Chi for 6 years to help with his allergies
and headache... when he's got his 'focus' neither have much effect on him
anymore.
