Unfortunately there was an assassin named Ezio that had actually discovered those paintings first but hadn't gotten around to telling anyone about them yet, and since he was an assassin he decided he was going to assassinate the boy.

Fourtunatly, Ezio died of natural causes before he could carry out his assassination mission.

Unfortunately, Ezio was in fact the boy's father

Fortunately, Ezio's death still meant the boy wasn't going to be assassinated.

Unfortunately, the boy was indescribably sad his father died, after all he had had no idea of his parent's evil machinations

Fortunately, in his grief, he acquired a drive with an uncommon intensity to seek out his mother who he never met, which he did, and they had a very happy reunion.

Unfortunately, it did not last long, since he had to leave.

Fortunately, he only had to leave for 5 minutes to put more coins in the parking meter and then he came back.

Unfortunately, his mother wasn't there when he came back

Fortunately, she actually was there, the boy just didn't see her at first because she was in the bathroom.

Unfortunately, he changed opinion of his mother as he heard her laughing with a man in the bathroom

Fortunately, the man ended up being his long lost brother who had been hiding in the bathroom for many years because he was afraid of automobiles.

Edit

Unfortunately, the brother had all of their mother's love for himself so the boy ran away from home

Fortunately, he only ran away in his sleep and dreamed of para-para-paradise.

Unfortunately, that meant his having met his mother was nothing but a dream. How sad.

Fortunately when he finally woke up, he was at his real mother's door step.

Unfortunately, when he awoke, he had a severe case of amnesia and had no idea who he was or where he was, so he stumbled very far away from his mother's house.

Fortunately his mother had seen him on her door step from her window and ran after him.

Unfortunately, she didn't see the tractor trailer coming as she ran across the street and got run over.

Fortunately there happened to be an open manhole in the middle of the road and she fell into that instead of getting hit.

Unfortunately, the fall left her with 42 broken bones.

Fortunately Coldplay came to visit her in the hospital.

Unfortunately, she had no idea who they were and shooed them out because she thought they were there to steal her purse.

Fortunately the boy who was suffering from amnesia was in the hospital and somehow recognised Coldplay, so they sang Fix You for him and then his amnesia was gone!
