In Friday's Casa Amor recoupling, Faye decided to recouple with new boy Sam but Teddy decided to stay coupled up with Faye.
Faye made her decision after seeing a picture of Teddy kissing another girl during a game of truth or dare at the Casa Amor villa.
In tonight's episode (Sunday), Faye and Teddy had a heart to heart on the terrace as he asked her: "So have you missed me then?"
She replied: "Well I did for the first two days and then you rattled me. I did miss you, but I was just being a t**t. Just putting my guard up and going, 'well f**k him then'. You can imagine it can't you? I was literally like, 'f**k him. I hate him.
"I came out here and just sobbed because I felt like I already knew what I had."
"What you had or what you still have?" Teddy asked.
"I don't know. I just felt like you f**ked it," she replied before Teddy said: "I feel like we both f**ked it."
He then made his move, asking: "Can I kiss you now?" before the pair embraced in a passionate snog.
Fans were over the moon to see the couple reunite, with one writing on Twitter: "Teddy and Faye to win, this is a true love story #LoveIsland"
Another added: "Faye and teddy rekindling things has single handily saved this whole week #LoveIsland"
"Crying happy tears rn , teddy and faye have just bagged 50k without realising #LoveIsland" added a third.
And a fourth wrote on social media: "Faye and Teddy just seem like a real normal couple and I want them to finish this journey out together. I really want them to work out #LoveIsland"
Can Teddy and Faye make it to the final?
