She suffered severe burns all over her back!Big fail. The blast blew out her freaking office windows and she walked away unhurt? Yeah, that didn't happen.
They never said what happened to her assistant who brought in the package.
Or the kid who was off finding lugnuts when his mom and John got shot up.
And whatever happened to Christina? Last we saw her she was pregnant with Jamie's baby, then she just disappeared.
Plot holes are annoying.
