Suki's relationships

Sokka
"I'm sorry I treated you like a girl when I should have treated you like a warrior." - Sokka to Suki in "The Warriors of Kyoshi"



The two bonded over sparring matches, and, before parting, shared what was presumably Sokka's first kiss. The two are reunited when Sokka and the others are on their way to Ba Sing Se in "The Serpent's Pass," where she and her warriors operate as sentries for the Ba Sing Se ferry. Suki expresses how important Sokka is to her and the two almost kiss, but Sokka draws back reluctantly. However, the next day when she bids him good-bye, she apologizes about the night before and he kisses her twice before she finally leaves.

Zuko



 * "Actually... we met a long time ago."
 * "We did?"
 * "Yeah, you... kinda burned down my village."
 * "Oh... Sorry about that. Nice to see you again." - Suki and Zuko in "The Boiling Rock, Part 1"

Zuko and Suki unofficially met during "The Warriors of Kyoshi" when Zuko attacked Kyoshi Island in an attempt to capture Aang. Suki and her team of warriors fought to stop Zuko's rampage as his firebending was destroying her village. They were hopelessly outmatched and eventually defeated by Zuko, but bought Aang and his friends the time they needed to escape. Although Aang extinguished the flames on the island, Suki held a deep grudge against Zuko for his attack on her homeland. Zuko's attack was part of the reason Suki left home to assist the Earth Kingdom in their war effort.

Ty Lee

 * "She’s one of us now." - Suki explaining the union of Ty Lee to the Kyoshi Warriors in "Sozin's Comet, Part 4: Avatar Aang"

Ozai

 * Yeah, or how about "King of the Guys Who… Don’t Win" - Suki to Ozai in "Sozin's Comet, Part 4: Avatar Aang"
