Question: Do "Bart to the future" and "Lisa's wedding" episodes share the same continuity? I only saw second one and I'd like to know if president Lisa is the same Lisa who was in love with Hugh, or Bart who has a band with Ralph the same Bart who used to demolish buildings etc? Or are they just independents predictions without connections? I'm not even asking about Future-Drama, because it'd be weird at this point, Lisa graduating in high school in 2013 and being at university in 2010.
Question: Has any episode revealed what Marge's natural haircolor is? In the flashbacks in "The Way We Weren't", she is shown as a child with blue hair, and it turns brown when another girl burns it. However, I saw another episode where she walks past her mirror, notices a brown spot of hair showing, then picks up a can and sprays blue to cover it up.
