What do you do vs Suicide Sion?

Sion did nothing but run it down for towers and because of Hullbreaker, became unstoppable in spite of feeding. I think he was 1-7 at one point pre-10 minutes.

I know part of it was that GP outscaled our entire team, but I'm just flabbergasted that a build like this was so successful. The only thing I can think of is that Garen needed to build Hullbreaker himself to match Sion, but that's out of my control as the jungler.
