I do think that it's possible
The Colony could learn of
the Tower's whereabouts. Don't forget that
Glenn helped
Michael send out a radio broadcast to the tower, revealing the Tower's location somewhere to the North. If a reconisance team from the Colony ran into some of
the Mallers I believe there may be a chance of an uneasy alliance forming between them to take out the tower. So we may see a reinforced army of Mallers vs. the Tower. Maybe.
Then there was that little prick of the ears by the doctor. She does seem to know
Saul. I don't know if she was anxious to see him because he was injured or anxious because she knows a soldier by the name of Saul. Man, so much to talk about but I'm going to halt it right there.
