Sontaran Encounter - (11th Doctor/River/Jack)The Doctor and River run into Jack, who's a bit befuddled about their relationship.Jack shot at one of the bulky figures over the wooden barricade he was hiding behind. Blaster fire and grenades exploded all around him, peppering him with debris.He ducked back behind his barricade and changed out the charge pack in his gun. A lanky man ran up, slipped in the shale, and joined him behind the barricade. The floppy haired individual stared up at him in shock."Jack! What are you doing here?" he said in a high pitched, surprised voice."Shooting people," Jack said, and took a couple of potshots over the barrier. "Who the hell are you?""Jack," the man said with a trace of hurt. "It's me.""Gonna have to be more specific than that," Jack said, sighting down his gun. "I know a lot of me's.""Oh, right, the face."Jack's head whipped around at that. He scanned the man in front of him, young, pretty mouth, thick hair, wearing, good god, a bow tie and tweed. "Doctor?"The man grinned.
