You are an inspiration to others. You can spend Fortune points on actions made by others, and this is cumulative with any Fortune points they may spend themselves. You also get a free Fortune point to spend each session on each character who has a strong emotional relationship with you. This is often a schtick for a romantic interest, but can apply to buddy-teams and rivals as well.
You need not even be present to use this schtick; if you can just describe a cut scene showing how you could serve as an inspiration, the schtick works. It helps if you give your friend a kiss, scarf, rabbit's foot or other token.
