Ves and his father ended their conversation at the same time he finished his work on the mech.
As much as they wanted to take the time to catch up on each other, his parents had to go. His mother not only scrambled the memories of his clansmen, but also made sure they woke up soon.
Once that happened, it was very inconvenient for them to witness Ves acting chummy with the leader of the Oblivion Hand and the energy projection of a giant monstrous woman!
Both Ves and his parents had several good reasons to keep their association as discreet as possible. Nothing good would come if the public became aware of the astounding events that took place during the battle.
Ves was only willing to let the first half of the battle go public. As soon as the Gravada Knarlax started spewing out different kinds of fog-like energy, he did not want the subsequent events to be leaked.
