Will and Lily aren't speaking. Worse still, Will is suffering adverse side-effects from protecting his friends from the rogue KT. Nick, fearing that he might not find a way to repair Will's nanobots, puts Eve on the spot, asking her if she can find Mary. Knowing the danger Mary poses, Eve lies - and tracks her mother down in secret. Meanwhile, cajoled by Abe, Lily finally softens and visits Will just as he takes a turn for the worse.
