When Rudy finally brought Ren and Fang home, everyone else was already up, and the ice cream they had bought was gone before they could say 'ice cream' (or 'happy birthday' for that matter).
Rudy, who had assimilated himself on Ren's phone as well, was introduced to his corporeal siblings – one human baby and three furballs. The amazing thing was that Rudy could actually converse with the furballs as if they were speaking normally.
Ren didn't understand how Fang had managed to achieve this – only people with magic could communicate with their three baby furballs – so how was Rudy, who had nothing to do with magic, able to do so as well?
To be honest, Fang didn't know the answer, either.
Ren wondered if Fang had accidentally infused some of his magic into Rudy when creating him, and thus, Rudy had developed his own independent existence as well as magical features…
In any case, Ren was quite pleased with the outcome and had no complaints either way!
