Editing Time Enough for Love (section)

==="Da Capo"===
In the concluding tale, Lazarus attempts to travel backward in time to 1919 to experience it as an adult, but an error in calculation places Lazarus in 1916, on the eve of America's involvement in [[World War I]]. An unintentional result is that Lazarus falls in love with his own mother. To retain her esteem and that of his grandfather, Lazarus enlists in the army. Eventually, before Lazarus leaves for the war, he and his mother, Maureen, consummate their mutual attraction, as his mother is already pregnant and so accepts that there is no collateral risk.<ref group="nb">The [[blurb]] of some editions (such as [[Ace Books]] {{ISBN|978-0-441-81076-5}}) states that Lazarus "became his own ancestor", but that is contradicted by the book, since his mother was already pregnant at the time of their encounter, and in any case, his younger self had already been born. <p>Heinlein's later novel ''[[To Sail Beyond the Sunset]]'', the memoirs of Lazarus' mother, also describes the events.</p></ref>

In the trenches of the [[Western Front (World War I)|Western Front]] in France, he is mortally wounded, but is rescued at the last moment by his future companions from the framing story and returned to his own time.
