He eventually relents and Krista tells him what she can, but she doesn't know about Blade. She asks him about the Leichen, who Shen says are vampires who have sworn off drinking human blood.

Chase arrives and they proceed with the ceremony.
Shen arms himself heavily while Steppin' Razor unchains Blade to take him to Marcus.

Steppin' Razor tosses Shen down to the ground, but Blade has enough time to recover and take out the other two Bloods.
