hmmm all the major deaths so far on the show have tied into the concept of family:
Phil dies out of sheer misfortune, but his last words are about his baby
Mike dies of the virus, but his last act is making sure his brother won’t witness it
and Gail dies because she was trying to escape her new family, as her first one was already lost.
(granted 2/3 of these people might not be dead, or might not be dead yet, but. sadness.)
