Since after Wilbur came back from the dead (he was revived), you made sure Fundy would never see the man that caused you and him so much pain.
The first day Wilbur saw you, you two argued, and the next time you met, and the next. Today was no different.
Exept for the fact you had no idea if Fundy was out or not, but ypu still where outside, arguing, with Wilbur.
When it just so happened Fundy managed to find you two arguing the exact moment Wilbur slapped you across the face, making you stumble back a bit, in tears.
Fundy was horrified and angry, who was this man, and how DARE he hurt his mother, so he launched forward and put himself in between you and Wilbur Fundy: "Who the hell do you think you are?!" Fundy shouted at him Wilbur: "Awh, do you not remember me little man?"
