Your mother found a stump that was all dried up but at the foot of the stump was a really weird seed. Half black with a blueish purple tent and the other half was white with sunlike colors. Your mother loved to grow strange plants so she planted the seed after she tour the world in search of strange plants.
The seed grew within a year to an average size tree at that time it started to grow apples, one side had grown black apples some with a blue tent and some with a purple tent. Your mother was doing research on the tree. {{she was in her 20s at this time}} Her brother came to visit and make sure she was safe your mother was at the testing stage for the tree and was going to try both apples.
Her brother did not like her doing this so he volunteered to eat the black apple mother was so happy to see her brother wanting to join. They went to the meadow where the tree had been planted the meadow was surrounded by trees which made it look beautiful. Your mother and her brother pick their apples and at the count of 3 took a bite from the apples.
Then all of a sudden nothing happened her brother was relieved nothing happened but as a surprise, they both tasted like normal apples she wrote it down in her journal. Her brother was a novelist of events that happen in the world and when your mother told her brother about the tree she grew.
He thought it could have been a seed from the skeleton brothers' tree, especially after what happened about two years ago. But her brother thought it could have been the failed recreation of it some corrupted scientist attempted. Your mother offered her brother to say the night and so he did.
Around the same time, she felt amazing the next day like her mood could never be brought down by anything. But her brother felt completely different like all the world's problems were crashing onto them and got sick.
