UPDATE: Success!! Convinced my girlfriend to calm down about the issue, and showed her that the snake has already calmed down considerably (although shes still very active and obviously still adjusting/stressed she is no longer striking blindly as anything that moves) It looks like all that worrying (on everyones part) was pretty much for nothing lol. Now my GF is still nervous but hopefully time and patience can make that work too... (And hopefully by then she'll stop calling me a 'rat murderer')
