Ah! The plot thickens!
The second episode is definitely an improvement. I like the music more here. It fits, doesn't cut in or out too suddenly and really gives effect. For example - in the flashback memory after Julian declares what his intentions are. You took your time with the drama here - that is very good.
Although still, the beginning seemed a bit rushed. POW! He comes out of the shadow! POW! Flashback comes out of nowhere. But it wasn't such a big deal if you don't think about it.
When you DO think about it, then Chase is awfully willing to trust The Dark One, isn't he? Just starts running off. Sure - he thinks that: "Can I trust this guy?" But that's AFTER he's gone running off.
Great improvement in your fight scene - but it felt kind of forced. Was the fight really necessary to the story? I understand you want to make your flash more interesting, but it seemed to be kind of unnecessary to the plot. I have yet to see Henry return in the series later... I hope he will though, or that scene would've been completely useless.
So again - I say - take your time with introducing new characters - building drama was MUCH better in this episode however.
(If my ratings seem unfair - considering the relative praise I give - it's because I'm quite rough in them. I don't want to give a good score, if you don't do an exceptional job.)
