But most were just fellow travellers in the outset. Boromir was going home and Aragorn was going with him. Gimli and Legolas were also on an indirect route home though there must have been a greater purpose since Gimli presumably let Gloin go home the more direct route via the high pass.. and while Legolas is alone it is possible that he hadn't journeyed alone. Gandalf is already a ringbearer which leave the younger Hobbits who go out of love and loyalty to Frodo.
