Okay. What does it mean then? Because what I had always understood "the spotlight" to mean is: Which character is currently acting, such that the focus of gameplay and attention is on them? That character has the spotlight. Other characters may be ancillary assistants, of course, but the character actually doing the important action is the one in the spotlight. E.g., a Fighter can be an ancillary assistant to a Wizard if the Wizard is the one casting a powerful spell, while the Fighter is keeping enemies at bay; or a Cleric can be an ancillary assistant to a Fighter, where the Fighter is carving a swathe through the baddies while the Cleric restores their HP.
