Since I seem to be one page behind in the commentaries at all times: Frankenstein's projectile blood vomit is brought to you by the fact that I watched Kill la Kill recently and have a somewhat unrealistic idea of how much blood a human has in their body. The amount of blood coming out of Frankenstein is a bit exaggerated, but for the record, she is still losing a pretty unhealthy amount of blood. Also, of course, it's not super healthy in general that she's vomiting up blood.
Also I hope it's reasonable to infer that Jekyll cleaned himself and Frankenstein up a little bit between panels 3 and 4--in future pages it became difficult for me to take Frankenstein seriously when her face was completely smeared with blood.
