Sudden onset projectile vomitting.
First sign something was wrong: moaning from Owen’s bedroom
Second sign something was wrong: Blech!
Time between first and second sign: one second, two seconds tops!
Stagger out of bed towards bathroom, but second occurence of projective vomitting occurs.
Zeke the WunderHund wakes up. Hmmm.
This looks like the beginning of a long night.
