What I didn't get?
How did Dean know when and where to meet Sam on that bridge? I know time is different up there just like it was in hell. The boys are not telepathic and don't have special powers to connect with one another. so how was this trickery done?
We don't know how old Sam was when he died, so therefore, we don't know what time had elapsed on earth to what it did in heaven at Dean's end. Sam looked old, but you just can't pin point an age, to be able to decipher the time lapse. This show is known for moving time on and not starting or finishing where we think it might.
So does anyone have a clue how Dean knew when to meet Sam, what date, what time in the future and we are talking decades not days, hours.... Because I sure as hell don't.
