A few minutes after Lilia left Aster finished talking with the twins, apparently this way of communicating through dreams was one of Aylin's abilities, when Aster asked them what did they obtained thanks to Aldebaran, they both answered "it's a surprise", before changing the subject.
Although Aster was quite curious about the result of their evolution so far, he didn't push them to speak about it, and instead he told them everything that have happened in the past three years.
Surprisingly the twins weren't surprised that new girls joined the family, that being said while Aylin was rather enthusiastic over the thought of having more "sisters", Alessia kept silent about it.
Even when their faces weren't visible due to the crystal cocoons that were covering their bodies, how could Aster not notice when a girl is jealous, an opportunity he took advantage off to tease Alessia.
