A new promo has been released for the final episode of The Big Bang Theory season 6, and the clip definitely has a certain “Wow” factor.

The Big Bang Theory season 6 will come to a close this Thursday night with “The Bon Voyage Reaction.” But hold back your tears, fans! As per usual, The Big Bang Theory‘s season finale looks like it is not one to be missed, so keep your eyes clear and dry – at least until it’s over. (We would include Raj in this particular prescription…but who are we kidding.)

Check out a new preview for “The Bon Voyage Reaction” right here:

Oh, Sheldon. You may be totally bonkers – drug smugglers know better than to park in the red zone – but we’re going to miss you as much Penny misses Leonard.

And speaking of that missing, is it too much to hope that Leonard and Penny reunite stronger than ever? After all, Howard and Bernadette made it through Howard’s astronautical adventures unscathed. Leonard isn’t going nearly as far as outer space, but has the relatively smooth sailing of season 6 about to hit the rocky shore of long distance?

Another question mark left by the promo is Raj’s blubbering tears, though the official summary for “The Bon Voyage Reaction” gives us an unhappy hint at what may be the source of Raj’s sadness.

A new success for Leonard makes Sheldon very jealous and throws Penny for a loop. Meanwhile, Koothrappali pushes Lucy too far in their relationship.

If Raj and Lucy are hitting the rocks as well, we may just need to have a tissue box handy! For a few more hints at what the season finale has in store, check out these promo photos from “The Bon Voyage Reaction.”

What do you think your reaction will be to the season finale of ‘The Big Bang Theory’?
