In the present Edit
Season One Edit
Leah attends to Naomi Putnam while she acts out the birth of her Handmaid Janine's child. She gathers around the food table with Serena Joy and Caroline, and asks June about the progress of the birth. She speaks in a condescending manner to June and urges Serena Joy to offer her a cookie, over the objections of Caroline.
Leah visits Naomi along with Serena Joy and several other Wives, shortly after the birth of Charlotte (whom Naomi names Angela).
When a delegation from Mexico arrives in Gilead to form a trade deal, Leah attends a welcoming ceremony for Ambassador Castillo at the home of Commander Waterford and later attends a banquet in honor of the delegation.
Season Two Edit
Leah attends Serena Joy's baby shower alongside Naomi and several other Wives.
Leah attends to Serena Joy while she acts out the expected birth of her Handmaid June's child; ultimately, however, the birth does not occur, since June is experiencing false labour.
Leah's presence at Commander Waterford's welcoming meeting for the Mexican ambassador implies that she is the Wife of Commander Chambers, since four Commanders (Chambers, Deeds, Waterford, and Putnam) and four Wives (Serena Joy, Naomi, Leah, and one unnamed Wife) are seen during the meeting.
