Who trapped Mac and Jack in Mac's house?
That was the big question on MacGyver Season 2 Episode 12 and things took an even more sinister turn when it emerged that the residence was rigged with explosives.
Not one to let an explosive get between himself and safety, Mace used a karaoke mic and an audio transformer to contact the team with some vital information.
While they were trapped, Mac and Jack chatted about the past and flashbacks showed viewers how they met all those years ago.
