Has any one else noticed reocering themes in hl I dont know if thay are on purpose or just me reading to deeply into it but I wondered so here are some examples. Transport: well first there is the portal/teleportation stuff but more importantly is trains, trains are evry where the bigining of hl1 and hl2 gordan arives by train at the end of hl2 g-man leaves and it is implied that he is geting off of a train in hl2 episode 1 there are to trains one about midway through and one at the end (ignoring Barny's train) so whats with all the trains. Black and White: where did this all start? at BLACK mesa and where does the final part of hl2 ep 2 where the super portal is closed and hope is given back to the peaople WHITE forrest im shure there are more and i would like to hear what other peaople have to say.
