Anderberry!Siblings, Klaine, Finchel
Blaine helped Kurt ease into Dalton life much easier than Kurt had expected to be possible. Blaine helped him with his classes even though Blaine was a year behind Kurt because Blaine had been tutored growing up. The time spent made it very, very easy for and attraction to build between the two of them. Kurt accepted his feelings and started to flirt frequently with Blaine. Blaine, on the other hand, was still under the allusion that he was in love with Jeremiah at the local GAP. Jer had helped Blaine accept who he was and was Blaine's first crush. The feelings Blaine was having for Kurt felt like Blaine was cheating a little on Jer. So the curly haired soloist forced the feelings down.
Sadly, though, Rachel's romantic life took a turn for the worst after finding out Finn wasn't a virgin. Their relationship fell into disarray, breaking the older twin's heart and the younger's heart to become hardened to Finn. It took all his willpower to not go straight to the Hudson-Hummel house and beat up Finn for hurting her.
Blaine didn't like keeping their sibling relationship a secret, but Rachel begged him to keep quiet for the sake of the custody case. It wasn't that they didn't trust their friends to keep the secret so much that it was a risk that someone would overhear them. Blaine heard about Jacob Israel too many times to risk it. The Berrys were trying to get their case together before informing the Andersons about the case to have surprise on their side. The twins' fathers still had a few months work before they could go to court.
Blaine kept trying to give Rachel advice on how to get Finn back, but sadly nothing he suggested worked. The hard part was that while he was seeing his sister hurt, Blaine was starting to fall harder and harder for Kurt, something he refused to accept still. Blaine even tried to sing a song to Jer with the Warblers, only to get the poor guy fired, something Blaine felt guilty about, but not as badly as he should have if he really was in love with Jer. The worst part of it was how hurt Kurt seemed to look while singing.
Christmas came and Rachel still didn't have Finn back, though she tried her best to win him over. Blaine on the other hand was inches away from kissing Kurt while singing to practice for his job over winter break. It was so close, it was all Blaine could do to leave as quickly as possible after the song was done without making it obvious. He called Rachel after and told her the tale. She, though heartbroken herself, decided right at that moment she would get her baby brother and her best friend together if it killed her. 'They say you should get a hobby after a break up. Well Blainey and Kurt, you two are my new hobby,' she thought with a smirk.
