Realizing this was not the time to debate about the future if he could not get Luke back there Obi-wan yelled to Luke "You take the the cabels and hook them up on the ground and I will set everything up at the top of the tower!"
"Fine!" answered Luke.
When Obi-wan Kenobi had fixed his end of the cabeles he yelled down for Luke to do the same and after doing so Luke could not hold what he had to say any longer screaming "Ben! Ben! On the night that I go back' but the storm kept getting in the way of everything and Obi-wan Kenobi could not heear him. 'You will be hunted down by Sith wanting to killing you for your experiments!"
Then suddenly lightning roared down Obi-wan yelled "Luke you have to get in the car now!"
Luke knew it was to late to tell him as he jumped into the car "Why Ben why? I wish I had more time. Wait a minute I have a time machine I have all the time I want. Lets set this thing to ten minutes to the previous arrangement. So that would be 1:25 instead of 1:35, that ought tro be enough. Alright the speeder is on. The fluxcapacider is fluxing and I have a full tank of fuel.' The speeder however does not start. 'No come on you can't die on me now' He bangs his head on the speeder stiring wheel and the speeder starts up again. Hitting the excellorater to go 88 parsacs per hour Luke races the maiche hitting the wiring just as the lightning hits.
Obi-wan is extracic back thirty years he has just seen one of his inventions work.
Luke gets back to his own time sees that it is only 1:25 then saying out loud as a bum calls him a crazy drunk driver "I've still got time!" Then seeing the Sith vechile that that was coming for Ben make the turn onto where the street that Luke and Ben were. "Oh no" Luke yells and begins to run toward himself and Obi-wan.
