This is more or less a topic to talk about what will evolve between the humans and the wraiths.
For example...I believe with all certainty that Season 1 will be mainly to build the characters personalities and relationship to each other. It will also develop a mystery and "creepyness" around the Wraiths as well as create feelings for those who have been pretty much enslaved for centuries by these creatures as a food source.
But...I think Season 2 will change this. I think that once SGA starts helping people...probably even defending them against the Wraiths on occasion in Season 1...then the Wraiths will begin to see us as a threat to their food source...and by that..they will see us as a threat to their existance. Which means they will be after SGA much more aggresively during Season 2 and very much so during Season 3. I know this is far in the future i'm looking...but it is fun to speculate...
I just don't see the Wraiths sitting idling by as we help their food source develop defenses to counter them.
