"Really? You slayed a behemoth? How?"

"I teleported into the library and found a Killing Curse."

"Hmm..."

"What's wrong?"

"Using the Killing Curse has been known to fill ponies with demonic rage, turning them evil. Make sure never to use it unless you absolutely need to, okay?"

"O...kay?"

"Good."

Starlight got curious about how the Killing Curse could turn somepony evil. The pony gave Starlight the promised quills.

"Maybe now that i've helped you, you can help me."

"What do you need?"

"I'm looking for Twilight Sparkle, know where she might be?"

"Twilight Sparkle? Last I heard, she was in Manehattan, I would have heard by now if she had gone anywhere else."

"NOW I REMEMBER! WE HAD BEEN HEADING TOWARDS MANEHATTAN TO GO TO TROTTINGHAM!"

"Trottingham? Yeesh! No wonder I hadn't heard, that place is too hostile for anypony to go there."

Starlight got worried, just to imagine if something might've happened to Twilight! But, she decided to calm down.

"I appreciate the help."

They headed for the Everfree Forest, because then they could go to FIllydelphia, and head for Manehattan from there. Once they were in the Everfree Forest, they encountered what appeared to be sunburned zombies with 'boiling' skin.

"OH NO! OZIES! KILL 'EM! KILL 'EM!!!"

Sweetie Bot gunned them down like crazy, with RPG's involved; now their all puddles of blood.

"Overkill much?"

"IT AIN'T OVER!"

They completely regenerated, Starlight got the Plasma-Epee; started hacking away at them all (this time, without Sweetie Bot firing anything). They didn't regenerate.

"WAIT A MINUTE! THEY SHOULD'VE REGENERATED BY NOW! THEY EITHER GOT DELAYED, OR THEIR GONE FOR GOOD. EITHER WAY, WE SHOULD GET GOIN'!"

She started running away; her guns still out. Starlight couldn't agree more, so she followed Sweetie.

Author's Note

Here's a couple of spoilers if you're okay with them: (Comments may contain these spoilers)
"Killing Curse"? By this point, those of you Harry Potter fans out there will expect a Cruciatus Curse and an Imperius Curse, those expectations will be correct. The Ozies are from an expirement Twilight preforrmed, in which she tried creating a drug that would give full immunity to the harsh sunlight; it... sort of worked. Sure now they're a new type of zombie that regenerates any wound like titans if blood shows, but they're immune to heat nonetheless .
