I think that the Nav card is incorrect because thats the Nav vard the Bus driver used to get to where he is now which is Green Run so he cant use the same Nav card to get where he already is right? I also think its because if you look on the clocks its about that time at night when bus route B should start right i think 9:30? So maybe there is no second bus and you're suppose to change the Nav card to route B. I think the only signifigance of the Nav cards now are for us to go back in time and use the Nav card for the bus earlier in the day perhaps when route A starts? And maybe we have to do something in the past to effect the future how it is now, by using that Nav card to go to the routes the bus driver talks about. Anyway thats my theory and thats what im.goin on from now unless someone figures it outout
