Lets assume your rings are OK and the valves are good, which is a lot of assumption. Verify the valves being OK by pouring about a table spoon of motor oil into #2 and checking the compression again. Using a drinking straw, about 2 inches of oil = 1 table spoon. If the compression goes up, the valves are good.

Unplug #2 spark plug and injector if you run the car on 4 cylinders. The car will cruise at highway speed OK, but with a significant loss of power.

It is always possible that #2 became flooded with gasoline due to a bad spark and completely washed to oil from the rings. But, you should have had a CEL pointing to #2 misfire.
