Sinestro Has His Own Batcave
The first thing that I noticed in Sinestro’s “Batcave” in Korugar are the Green and Yellow Lantern batteries prominently displayed. Since I know he keeps his batteries in the pocket dimension for easy charging anywhere he goes, those must be replicas.
And if he has replicas, then he must be sentimental. 😀
