You had just taken a bullet to the shoulder by Kenny after jumping in the way for Nifa

While Levi pursued Kenny and his crew, Nifa fell back to give you medical attention, or at least, the best she could give you

"Soldier! Come on, stay strong! Don't freak out, I got you!"

She says as she removes the bullet from your shoulder. After that, she places your own hand on your shoulder before looking around.

"Shit... Keep your hand on the wound! I'll get you something to patch that up!"
