I don’t understand…

I don’t understand how Conrad didn’t pick up on the vibe and tension between Jelly and how they were becoming close again in season 2! I mean I know he had a lot of stuff going on in his head and was focused on the house stuff, but the vibe and chemistry was blaring obvious especially since the boardwalk! The looks they gave each other, the hand holding and looks on TOT. Jere cheering her on at shoot your shot, them laying next to each other on the golf course arm around her in party city, the flirting with the slurpy, The bear hug when they were studying just to name a few. I mean how could he not notice even just a little bit?? I find it hard to believe he could be so clueless with it!
