While I was re-watching episode 2, I thought about the idea that the lights Clem sees by the bridge may not have been Carver's group.
- Matthew tells Luke and Clementine that he sees a group every day move through there,
- There is no real proof that those lights were from Carver's group (or at least that I know of).
- When you speak to Carlos, Alvin, and Rebecca at the lodge, the options were: I saw lights, Someone was tracking us, and It could've been anyone.
This just an idea and odds are it was Carver's group, but do you think there is still a possibility of it being someone else? (Perhaps characters that may be helpful later on)?
