Ok...this is out there, but I conjured this up on the bus late tonight. Remember at the beginning of the ep when Syd says something about it being the longest debrief ever...or something to that effect? Did it not seem to you that the sex scene, while very fun, was entirely misplaced and an odd choice for opening a season finale? Is it possible that the debrief she references at the beginning of the ep is the debrief Syd undergoes after this 'absence,' perhaps...after this meeting with Vaughn at the end of the episode? Hmmm...let me analyze the tape again. I have not watched it again yet. But what a hell of a finale! Honestly.
