I'll be waiting

Rachel was running through the hallways of the broken base, retracing her steps towards the place she last saw her father. When she got to the place he last saw him, the shutter doors were still closed, but unlike before this thing wasn't going to stop her. Rachel activated her [ability] and punched the shutter doors with burning flames, melting the door. 

...

While Alex and the others were trying to catch up to Rachel, Oliver saw something in one of the rooms. He stopped running, which made everyone except for Alex to stop running as well. 

"Oliver, what's wrong?" Sayaka asked.  

"You guys go ahead, I want to check something out." 

"Are you going to be okay?" Niel who also noticed what was inside those rooms had a few guesses as to why Oliver wanted to look. Knowing how extremely perceptive Niel was, Oliver, nodded his head and answered, "Yeah, I'm going to be okay."
