Of course he appreciated the help. Who wouldn't, were they in his position? Injured, looking for medicine, cornered by zombies. Yeah, anyone would appreciate a bit of assistance. Well, maybe not anybody. Leah would have, though, although she would've made a bigger point of not outright asking for help.
She rolled her eyes at his response, sighing with exasperation. "Then I make no guarantees for getting you back somewhere safe." She wasn't strong enough to carry him back, and besides that, she wasn't the type to give anyone a piggyback ride — with the obvious exceptions being her sisters and brother.
Leah stared in disbelief when O'Brien explained that he'd passed out in the middle of a store. "You must be the luckiest son of a bitch in the world." She shook her head, muttering, "Passing out in a store and no zombies coming to munch on you..." That was unbelievable.
"Let's go, then. I'd like to get back before morning, at least."
Rooftop travel was the safest method, second only to supply trucks which were used almost exclusively for large units of immune when they ventured into the city as a group, searching for bulk supplies. In no time at all, Leah and O'Brien were on the front steps of City Hall, waiting for the guards to clear a path into the building. Leah parted ways with O'Brien, making her way to drop off the medical supplies at the infirmary and then heading off to find a place to sleep for the night.
