Good catch! Someone mentioned on the main Fringe thread a while back that there have been hints all the way through the series like this, specifically of the episode names being mentioned somewhere in the background of the predeeding episode. I love how they put in all the little easter eggs like this & the code & the watcher in the background. 
Good Eye Badger! Most times I miss the next episode clue.
And yeah that was me who mentioned it in the main thread. I like it that they incorporate such little things like they did on LOST.
Yeah Badger, good eye! 
Next episode clue. Wow. I love this show more and more each day.
Frak! I really should let the Tequilla bottle leave before noon.
Don’t fret. And Tequilla should be allowed to do whatever it wants. Besides, it’s going to do whatever it wants anyway.
