On demand I can only get season 1 # 1,2,3 &4, how do I get the others?
Currently, I am only seeing episodes 1-4 as available for this program. The network makes programming decisions about the availability of on demand content. In some cases, additional episodes may be available using the network app directly.
You should be able to find them on TNT website. If they aren't there anymore and you really want to watch before TNT runs the repeats, probably shortly before the new season starts you can get the entire season on Amazon Prime video. It's not an included with Prime series though so you'd have to pay for it. I think it's around $23 or so. Or you can rent/buy individual episodes.
