I'm sure the show runners realized they made a big mistake when they cast this guy as Barry's dad; He can't act for ****. He is so one note and monotone; if it wasn't for G. Gustin's acting that final scene would have completely missed the mark. Seeing him try to show emotion at the end of the last episode was painful to watch- it was so forced. He was in season 1 for like 2 episodes, and when they brought him back for season 2 they purposely kept his lines at a minimum- in fact i think he said the most in the last episode then any other episode he has been in (much to my dismay). Its pretty obvious why they chose him to be killed off. They could have had zoom kill any of the characters Barry is close to (iris, joe, kaitlin etc.) and it would have had the same impact.
