it like back in the day, and various characters could live there, and they could have random cast interaction. Lucas living in one of the apartments at a Liz-owned Brownstone would make much more sense.
To quote Scotty Baldwin, these writers don't have the sense God gave a goose (so lock them up in Sing Sing.)
(I wasn't watching at all when Liz somehow got the Brownstone, no idea if it's still her's, nor how she got it. I just remember looking on the GH wiki to find out what happened to the Brownstone and she was the owner.)
