I think that Lincoln Lee (the alter-Fringe leader that got cooked) will play a part in helping Olivia escape and it will have some connection to him
having recognized Nick Lane. I hope we also find out what the deal is with the scar that Nick Lane has and why is it identical to the scar that
alter-Charlie has? Isn't that also how William Bell told Olivia to identify Newton?
The glyph word for the finale was "Weiss", as in the guy from the bowling alley. On the chalkboard in Walter's alternate lab is written "A
Demon's Twist Rusts" which is an anagram for "Don't Trust Sam Weiss".. very interesting!
