In the episode "Missing Linka", Linka spends most of the episode running around by herself. While she's inside a mine, she falls and gets knocked unconscious. She's saved by a mysterious bundled stranger (not for the first time that day either), who runs away after she comes to. It's later discovered that the mystery man is none other than Wheeler. She even kisses him for the first time to thank him.
Wheeler not only talks Gi out of outright killing the guy who shot her friend, but even hugs her as she is crying into his chest.
In the episode 'The Great Tree Heist,' Captain Planet is so badly injured by Greedly that he is unable to be summoned, leading to the Planeteers thinking he's dead. Later, Captain Planet is summoned in time to save the Planeteers from being killed by Greedly. After getting them to safety, Gi and Linka jump out of the Geo-Cruiser and run into his arms. Captain Planet hugs them back, looking like the happiest person alive.
