I just recently started to watch (struggle) through babylon 5 - and one quote at the end of an early episode caught my attention:
"There's something in my head. It says .. maybe you're still inside. Maybe we're both still inside." — Knight Two in Babylon 5:"And the Sky Full of Stars"
I tried to look up some informations about this, but I couldn't quite find anything yet. No relevant wiki trivia or anything - just a repeat of the quote.
Is this ever followed upon or mentioned again later in the series? Are they?
Judging by the episodes following, I'ld say it's unlikely that:
They are all just a [virtual reality / dream / whatever else] the quote implies.
