<P> Episodes in the series subsequently follow Sam 's reaction to each leap ( typically ending the cold open with him uttering `` Oh , boy ! '' on discovering his situation ) , and then working with Al and Ziggy to figure out his new identity and whom he needs to help to `` set right what once went wrong '' and trigger the next leap . An episode typically ends as a cliffhanger showing the first few moments of Sam 's next leap ( along with him again uttering `` Oh , boy ! '' on discovering his situation ) , which is repeated in the following episode 's cold open . Though initially Sam 's leaping is believed by Al and the others on the Quantum Leap team to be random , the characters come to believe in later seasons that someone or something is controlling Sam 's leaping , and this is a central focus of the show 's finale episode , `` Mirror Image '' . </P>
