This Blood is Thick abruptly ends the spectacular JH Williams III run on Batwoman. Shame on DC, the title went full south afrerwards. After the Medusa attack on Gotham, you know that another epic story is building up again, one that is more personal, one that involves Batman himself. 
 I love where the series is going, the marriage, the battle of the Bat-cousins with all other supporting characters thrown into the mix. Volume four sets all that up, giving us an exciting preview on what the Batwoman series can offer - the Kate-Sawyer marriage, the DEO, other members of the rogue's gallery and Batwoman's interesting relationship with Batman. The next arc could be what JH Williams III has been building up (with Rucka) since Elegy - the last arc towards a full circle. 
 But unfortunately, things aren't good because DC wanted Kate to join the mainstream Bat-stories. D*ck move New52 DC! 
 Artwork isn't Williams' but still way better than that of volume 2. You get an emerging trend here. Volume 5 MIGHT have been drawn by Williams. Shame we didn't get to see it. 
 This Blood is Thick is much more personal, a start of a could-have-been-epic story of the Williams Batwoman run. This is the farthest it will take us folks, appreciate it, then stop reading the succeeding issues.
