Jim noticed Steph looking around, not for zombies, but for something. He later realized that she was unarmed. Jim took out the small pistol Spencer lent him, nodded at Spencer then called Steph's attention. 

"Hey. Take this. Spencer let me borrow this before we split up, and I think you'll be needing this more than me." Jim said as they continued walking. "Thanks Spencer, I hope you don't mind her using it. There's a few rounds left."
