Oh, Kerrigan can relate. Good call on Need's part to defuse the xenophobia.

"Hey, kid," she says. "I don't know if Need told you, but I'm Sarah Kerrigan." Kerrigan looks like she's just dropped in from somebody's crossover fic, because she herself has an elven sword hanging from an equally elven belt at the waist of her not-at-all-elven sci-fi armor. She offers a gloved hand to shake before she notices the layer of blood crusted on it. "...Oops."

Retracting the handshake, Kerrigan instead crouches to grab some playground sand as a makeshift scouring pad.
