Blake managed to track down Dawn and his mother's scents that led him to Lyra's study room, the place that held so much memories for both of them, because they used to be here.
Blake would come to find Dawn with Lyra after his training when they were teenager, because Dawn was so close to Lyra and learn a lot of things about medicine and apparently, poison as well, from her.
"Dawn, do you remember this place?"
"Oh, please stop with that. You look so pathetic when you reminisced the past." Dawn knew what Blake wanted to say and she felt throwing up if he kept talking about the memories that they shared together.
Blake's face turned red, he was embarrassed with Dawn's respond. Good. At the very least, he was not as shameless as Dawn thought he was.
"Mother, take her to me," Blake ordered Ava, he shifted his attention toward his mother, who was standing next to Dawn. "Take her to me and we can go together now."
