The Green Arrow is looking for Solomon Grundy for reasons unclear. He finds himself saddled with a scientist from S.T.A.R. labs who claims Grundy is her great, great grandfather, and that she has a serum which will rid him of his beast-like appearance. Dr. Chrissie Cavendish hopes to return her alleged relative to normal. In searching for her relative, she and Queen share an ambiguously romantic evening in the forest. The next morning, they find Grundy and she attempts to use her serum. Unfortunately, Grundy becomes agitated and she ends up injecting herself.
An odd issue. While much of the rest of 2005 had been a continuous storyline, the writers left a cliffhanger end in issue 52 without comment in this issue. They would return to the storyline in issue 54, so it's difficult to figure out where to place this issue in Oliver Queen's time-line, except to say that it occurs sometime after his resurrection in issue 10.
