This is a cliffhanger if I've ever seen one, and three things can happen.
1. It can be played straight, Qarr persuades V to team up and V's slippery slope becomes 30 degrees more steep.
2. It can be played straight, Qarr offers his services, but V refuses and zaps him.
3. It can be averted with V completely ignoring Qarr, or even Qarr not being able to catch up to V's fly speed.
Unfortunately, my gut says 1 is the most likely option.
EDIT: Crackpot idea
4. The comic switches suddenly to Haley/Xykon/LG, and we don't find out what happens for at least 20-30 strips.
