oooh, wild medival jils to contend with where Ed and Loreen are... and Karl getting nabbed by his own mind back to his captors... I have to admit that I am not going to be very patient for the rest of this.
Almost. Sam is Karl's power pack. It was just luck that Loreen turned out to be linked with both Ed and in a less powerful way, with Cory as well. However, Ellie is linked with Karl in the more standard "two-psychic" partnership.
