Though Leah peed multiple times during the trip, she didn't poop a single time. She held it in, planning on using an actual toilet once they arrived. But then she was put back into a diaper, and now the situation is getting increasingly urgent. Leah crosses her legs, trying to hold it in. Maybe she can hold it back until after Tina and Robert pick her up.
