Loki waved farewell to Rocket,Lylla, Teefs,Floor,Gamora and Yondu. They all waved goodbye,knowing that one day,they will meet again.
As the crew of ghosts visited Earth, they saw Peter Quill crying. As it turns out, his grandfather died. The crew and Quill hosted a funeral and everyone from knowhere and the guardians as well as Mantis attended it. As they all mourned the death of Peter's grandfather,it felt like deja vú as they literally just mourned Rocket earlier this morning.
As the crew of ghosts prepared to head back to Earth,they promised to visit Quill and all the guardians,former,old and new. Before they headed back,Gamora and Peter Quill shared a kiss.
