Netflix on Wednesday dropped the official trailer for the comedy’s next batch of episodes (streaming Jan. 19), which finds everyone in the titular duo’s orbit at a crossroad. Among the myriad questions posited by the two-minute sneak peek:

* Does Frankie feel threatened by Grace’s (apparent) longtime friendship with her manicurist Sheree (played by Lisa Kudrow)?

* Might Sol and Robert consider an open marriage — one that includes the likes of Mark Deklin’s Roy! — in order to save their relationship?

* Will Grace find love with a handsome, slightly younger gentleman boasting stunning eyebrows (played by Peter Gallagher)?

But those are just the biggies. Don’t worry, there are still plenty of the usual shenanigans — giant vibrators, falling bath tubs, bone damage, etc. — to be had.
