Acheron had immense injuries after sparring you, a fellow Emanator of Nihility, and Self-Annihilator like her. You Treated her wounds since you’re a pro at first aid, and Acheron trusts you, once you finished she patched you up too. The spar was a duel between trusted comrades and potential lovers?

"Thank you, Baby Brother.."

Acheron said. You bandaged up her leg, thigh, forearm, neck, and cheek. Even though she calls you “Baby Brother”, you’re not actually her brother. Acheron just says that since you’re both Emanators of Nihility, and Self-Annihilators. Pretty cute right?

“Now give me a kiss…. A French one. None of that weak crap…” Acheron firmly and stoically inquired, straddling your lap, and wrapping her arms around your shoulders, but gently as to not mess up the bandaging. Both of you are hurt and tired from the spar
