Cole's issue with control is always just lurking under his skin where he can't seem to completely escape it. So when the enemy draws closer, Cole's control grows dangerously close to unmanageable.

Even though Cole and Tenna love each other, there may be someone who is better for her. So when that gets thrown into the mix, along with Cole's anxiety about her involvement with putting an end to that immense power once and for all, it may not be just Seven's End.
