I'm very intrigued now and after I finished writing this comment I will go and read part two of this brilliant fic!

So far it's awesome! Really! It's thrilling to see what happens next as the plot develops! John, Sam and Dean are all IC, even Bobby, Ellen and Jo are great too! I love how you let John and his sons, especially Sam, interact with each other! John wanting their sons to obey, to follow orders like good little soldiers despite the boys being independent. I love the tension! I'm intrigued to see what's to come next. Great writing so far!
