Ok, there was this episode where Matt and Sora revealed their love towards each other, but I don’t think it aired in either the US or the otha countries apart from Japan obviously. I think it was a valentines one, but I forgot. Read it on Wiki, that place knows everything! And honestly I love Tai and I think he should of paired up with Sora instead, but Digimon's so unpredictable!
Keep Smiling! :)
