The glyph on tonight’s Fringe was “REVEAL.” To me, this is similar to the glyph for “Snakehead,” which was “HIDDEN.” Means relatively little. However, it possibly refers to the reveal that Olivia experienced at the end of the episode, when she discovered that Peter had the “glimmer” of someone from an alternate universe. It could also refer to the inevitable reveal that Peter will experience when he is told, by Walter or Olivia, that he is from Over There. The third and final meaning for the glyph could mean that the audience is in for a big “reveal,” plot-wise in the episode. All three are viable options, and are probably the most that can by extrapolated from this vague glyph.
I’m ready for them to tell us that all the glyphs some big sentence or something.
