I don't recall that but there have been hints when they were resting on those trees and waiting for the sun to set Ymir told Reiner "the Titans back at Utgard Castle could move fine at night" and he replied "Titans here don't move at night. Shouldn't you of all people know that already" and when she told Eren "if you think things would end by killing those two you're mistaken" I don't know if this means she saw Marcel's memories of the Hometown and its people but  other than hints here and there and just beating around the bush,  nothing directly confirms it.
