Nothing about what you typed makes any sense at all. If they were willing to help you with the first parts of the raid, which means they said they will run the ENTIRE raid with you, then WHY did you agree to run the end first with them to give them what THEY needed? I would immediately think they were gonna bolt after getting what they want. Gen Z dont give a dam% about anything but themselves. In my mind only a child or someone very nieve would agree to this arrangement.
