Hulk (2008) #10 was great fun, Defenders (2005) #2 was insipid trash. This book is somewhere in the middle.
Each character encounters something he wants very much. In effect, he is taken to his proverbial happy place. For Namor, naturally, that means encountering his former lady love, Dorma.
The next part is a little unclear to me. Silver Surfer and Doctor Strange deduce that an alien ship was separated from its fleet and its passengers tried to bond mentally with the people of Earth in order to rebuild their society. This is what caused the "happy place" effect.
Unfortunately for Namor, the first teammate he freed upon breaking the spell was the Hulk. The green giant was none too happy about having his fun ruined (being yanked from his own happy place) so they started throwing down.

While these two pound on one another, Strange and Surfer quite simply solve the problem by sending the aliens home. The experience has had some impact on our favourite prince, however.
Not a bad book overall but by no means a classic. I would be surprised if this story was every referred to again in continuity but I'm sure if you're a fan of The Defenders, it made for a good nostalgic read.
