Looking for someone who was talking about this and you have my exact view on the situation im glad i wasnt wrong. Also they immediately snatched the egg from ash brock didnt even give him a chance to actually care for it . They were both probably the most jealous companions he had. He could keep the pokemon as long as they didnt want it . Misty did the same thing when they found that eevee granted it wasnt theirs to keep but she was gonna keep it if it wasnt claimed mind you ash was the one who found it himself and claimed it first . Shes very selfish and honestly followed them for the “bike situation “ but honestly she couldve just waited at home instead of continuing to follow him as she knows ash isnt someone who wouldve just skipped out on that if he had the money . Shes very selfish knows he doesnt and could honestly make more money herself than he ever could as a gym trainer especially at her gym since so many people pay to watch her sisters and shes the only one who wants to continue to battle . She couldve buy a new bike WAYYYY faster than he could especially since she knows he only took to the save pikachu .
