I like that Baam doesn't think that him and Rachel working together will suddenly fix things. The panel after that made it seem like they both are upset over that fact. But at the same time, I wonder if Rachel is upset about it or if she's upset Baam has moved on from her, essentially. Although we know she hasn't yet be able to kill her emotions yet like she wants. It'll be interesting what type of changes Rachel goes through, whether it's further toward darkness or something else.
Baam being able to kill the immortals, is not surprising, but still kind of surprising. It's only surprising in the sense that magic/spells have appeared to be different from regular shinsoo and it was said that a stronger spell is needed to break a spell i.e. the 13th months needed to kill the immortals. It also seemed like spell/magic were brought into the tower from the outside, and might not be affected by an irregular. But maybe since it was an irregular only technique it still breaks everything. Furthermore, Urek's attack didn't fully work which he attributed to Karaka using a spell/magic, so maybe irregular attacks break spells.
I like Karaka a lot. Even though he can't match up with Urek at all, he still stayed calm and came up with a plan B. It also shows that while people don't know Urek's face they all know his personality and legend. Karaka, quickly abandons the situation with Haoquin. It appears when he loses his body all the takes with him is his head and the ring, which Wangnan finally noticed.
So Urek, basically enabled Hell Joe by recklessly using his powers. I hope this is a chance to speak with Baam about the consequences of recklessly using power. Also the fact that Urek acknowledges Joe makes it seem like the others are sleeping on him. Although it would be interesting if he let's the 2 people he's acknowledge in this sense Baam and Hell Joe battle it out.
I think there will be a lot of twists this arc and hopefully we see more high ranker battles.
