It was absolutely stupid - Iop didn't even know for a long time that he was a god and that he had children with Evangelyne. Only here you were strong enough (or insane) to follow the Brotherhood of The Tofu to the Tower of Dreams. Of course, it was much easier to get after them, but you managed to get to your father! At least you were running in his footsteps.
Evangelyne's tower was collapsing due to childbirth, and you had to speed up your pace. If you wanted to say something to the father, you just planned to find him before the place disappeared or he died again. He didn't realize who was following him, but you quickly brought him back to his senses by grabbing him by the collar and trying to communicate with him (as much as you could in your situation). About how bad he was for completely forgetting about you and a lot of other things... But he seemed more concerned about the cry of his newborn baby, which Rubilax helped him remember, because he was willing to accept the squealing in the distance as the squealing of a pig.
Goultard, who had been standing nearby all this time, was watching you, but he didn't intervene. Percedal was more concerned about his wife (who had just given birth!), but he was still reachable. He stared at you, blinking almost in confusion, "Wait, did you just call me 'dad'?"
