script or unknown?

Did Jesus, as a man, know everything that was to happen to him? Or was it following God’s leading as he walked that path? I just read in Matthew about his betrayal. Did he know who would do that to him before judas had decided? Or did he just know that one of them would? He knew death was on the agenda, but did he know the rest? The scourging, the carrying his cross, the spitting? Did he know before and therefore just acting out the drama, or did he feel the fear of the unknown? I have always assumed the whole thing was scripted in heaven and Jesus just walked out the script. What if that isn’t the case? What if he had to ask for every bit of strength and wisdom from his Father?
