will and abigail sneaked out for mcdonalds at 2 but encountered hannibal in the parking lot with everything he needed to vanish an army in his bentley trunk. and abigail realized before will, it was bc hannibal thought will was leaving him, instead of worrying about their safety.
It feels that Hannibal hides his deepest emotions (love), contains them, because they are so strong. When he lets them out - destruction ensures. Either of his own self preservation or of the lives of others.
