User blog:The Demon In Me/Bobby Singer

So when Bobby was a ghost he was unable to bee seen by anyone, he had limited power, was intent on helping to kill the leviathans. However in "Of Grave Importance" he was able to be seen by Sam and Dean. I think that when Whitman Van Ness tried to absorb Bobby, but was Interupted Bobby ended up absorbing him, amping up his ghost power and then speeding up his transformation to a vengeful spirit (which Tess claimed took years.)

What are your thoughts on this?
