Xavier went to the nexus tower to take Lyra with him, but the apartment was empty.
He called Lilia, and she told him that she and Lyra had gone out because Lyra wanted to see the city.
Xavier asked for their location and told them to stay there.
A few minutes later, he got there and scolded Lilia for taking Lyra out without informing him.
He then told them he was going on a short mission and he needed to take Lyra with him. Lyra, of course, was excited and immediately hopped onto the bike.
"When will you be back?" Lilia seemed sad, but she didn't say anything, nor stopped him.
"It's a 200 kilometer ride, so three and three… six hours just for travelling. Let's say seven since we might have to stop once in a while. And then another two hours to find the fragment. So… if everything goes right, we will be back in ten to twelve hours. Around midnight."
