Returning to the ship, Picard and Data must find a cure while avoiding being killed by a heavily armoured prehistoric Worf. Journey's End A sullen Wesley Crusher returns from Starfleet to the Enterprise. Wesley's exam grades and ratings are dropping, and his rudeness now even extends even to former best friends.
