Looks like a promising arc. I found a pretty tantalizing image in the Green Lantern Wikia. I would be surprised if there aren't more scenes across the lantern comics that include this arc:

I've got it. There are 2 versions of the picture on the wikia: One in #3 and #11. I'll post both tonight. Thanks for the heads up.
