Princeton Video Confirms Plot Point

Spoiler Warning (for those that don't recognize the whole site as a big spoiler).

PhillyFilmGirl has posted another video from when Transformers 2 visited Princeton to film Shia LaBeouf's Sam going to school. The video is a continuation of footage that she had posted back in June. This time the video captures dialogue being filmed for Transformers 2 scene that supports a plot point revealed in June that maybe Sam is losing his mind much like his great great grandfather had after interacting with Megatron.

Thanks to PhillyFilmGirl for the video.

Update: YouTube pulled the video, so PhillyFilmGirl provided the alternative above.
