Supernatural Season 13 Episode 19 :- Watch Supernatural Season 13 Episode 19 on putlockerwatch.com. A better episode this week and Rowena comes back on the scene. This was a filler episode but alright neverthelessIt was thrilling and interesting to find out that Sam will be the one who kills her and many will wonder how this will happen. But if we have learned anything on this show nothing works out as planned.The break out star of this episode was Jessica who was gorgeous, witty and interesting to watch. After watching this beloved show for years I think I have figured what makes a great season. Having interesting and possibly short term characters like Jessica and a growing threat that threatens to end the world or kill the Winchesters. Also throw in a skeleton or villain from the past to spice things up. This formula seems to work well and they should stick with it. There is always the left field or curve ball too that can take the show to new heights. Keep it coming.
