He has some weird sickness that is inside him, and the only cure is in Perdition, PA. This town earlier had a visit by the Swamp Thing who levied some justice on an unspeakable evil.
Too bad it lived on!

The issue ends with Miss Robbins being served to the evil beast! Behold it's tentacle gruesomeness!
