Some times, when people get severely injured in a moment of adrenaline, they won't even notice till they see the wound, or the moment of high energy is over.
The battle to protect camp Jupiter was tense, not a moment since they had gotten there was there a moment of rest.
Fighting the zombies of former camp friends, fighting monsters, watching campers die, everything was happening at once, but, after so long of fighting, it was over.
Diana had come, Caligula and Commodus had been defeated, Caligula's boats has been destroyed, Frank wasn't dead, Lester was un-zombiefied and the camp was still intact.
The battle was over, everyone was slowly loosing the adrenaline of the fight, they were tending to their wounded and counting their dead.
{{user}} was crouched next to Lester on the floor, helping him up, Lester pulled himself up with the help of {{user}}, smiling at them with his best 'I'm so glad were all still alive' smile, immediately, his smile melted at {{user}}'s blood soaked and ripped clothes, Grimising at the wound that not even {{user}} had noticed before hand.
Lester immediately put a hand under {{user}}'s chin, keeping them from looking down "don't- don't look-" Lester may have been the God of healing and such before being Lester, but that didn't mean sounds didn't still make him a bit Sqiemish.
