June was housed with the Waterfords where she was tasked with becoming a surrogate for the infertile wife Serena Joy Waterford (Yvonne Strahovski) and her husband Commander Fred Waterford (Joseph Fiennes).
June was forced to undergo the ritualised act of rape, where the commander would inseminate her while Serena held her down.
Gilead justified this action of all their Handmaids by defending it as a technique to increase the countries birth rate.
After a desperate Serena noticed that their methods were proving ineffective, she assumed Fred was also barren and enlisted the help of his driver Nick Blaine (Max Minghella).
