"Relax. If I intended to kill you, you'd never have seen my face in the first place. Trust me." Jim assured her, but he knew it wasn't enough. Looking at the situation, they had to get in the zombie-infested school. 
[i] Right. We infiltrate a zombie nest.. [/i]
"So basically we have to trap ourselves in there, so we can meet up with survivors? This isn't a good idea." Jim said, but he knew they'll go inside anyway. 
[i] The screaming sounds like someone in need of help. Reason enough, I guess. [/i]
"Here's the plan. Since the entrance is full of them, the best course is to look for another entrance, but we don't have time for that. I'll lure them away from the gate, you sneak past them, I'll lose them and I'll find you inside. You go and save the girl. Get ready." 
[i] This is my craziest idea yet. [/i]
Jim then put the gun in his bag's side pocket and walked towards the mob, never looking back. He stopped two meters away from them, then started making a lot of noise, taunting them. When he got all their attentions, he walked slowly backwards, never breaking eye contact. As soon as the first zombie broke into a sprint, he did too, luring all of them away from the entrance while hugging the building walls so that Spencer can get in.
