"I know," Jason said. "I'm sorry, the CIA decided they were especially keen to get hold of me and my abilities so sent almost everything they had against me short of the Unters themselves. At the time they didn't know about your powers so I thought you were safe, but then Cypher discovered they'd been tipped off by someone, I don't know who. I knew they'd try to use me to get to you if they realised we were siblings so rather than risk your safety I went into hiding, leaving my necklace with Cypher so you'd know I was still alive. Eventually I ran into Shauna who said she had a way of keeping me away from the attention of the CIA and...well, let's just say we've grown very close since then," he said, blushing slightly.
