Family from the past

Julie was still in shock, not knowing how to perceive what she saw and what the woman spoke. The woman looked younger, and it had taken her more than a few seconds before she came to believe that this woman was indeed her mother. 

"Are you sure about it?" asked Melanie, raising her eyebrows, and she looked in the direction where the woman had left. 

Julie nodded her head, "Yeah, I am sure of it. Her features, they are all the same." But if she had come here at this time, it only meant that she had moved to a timeline which was far beyond the time that she had expected to visit. It didn't seem like her mother was married to anyone or had any children yet. "I don't know what caused the portal to open. There must have been some sort of trigger for it to happen." 

"But we were only walking on the bridge. Was it because of the echo of the memory?" asked Melanie, slightly worried.
