Okay dude, no, your blood's the same color as mine, why would it freak me out? It's just jeeez, I sure wasn't expecting it to be coming from your eyes! I didn't know trolls cried blood, that sure is weird!

[you wonder if trolls need a blood transfusion if they go through a really bad breakup or if there's a death in the family. you decide now is not the time to ask!]

It's not a big deal, Karkat! You're just experiencing a major case of the feelings, I guess! It happens to everyone!
