If only it were about a pulse. Life would be so much easier that way. Unfortunately, Karl's issues are far more complicated than pulses. Does he actually want to spill everything to Lyall, however?

The decision reached is ultimately a yes. Not only had he lied to the guy too much as is, but talking with people about this might help with figuring things out. Saying everything or telling everyone won't happen (too dangerous), but telling a few people some details can't hurt. Karl nods before looking up at Lyall. He opens his mouth, closes it and then opens it once more. "I found out that my son's alive."
