It was just treated so lightly in the moment that it felt crazy to me. Not as crazy as Sarek and Amanda abruptly popping up just to give her a farewell hug and then tapping out within a few short minutes.
It kind of presages what happened in the finale with the Calypso tie-in.
Gotta do something nonsensical, so best to do it as quickly as possible and hope the audience forgets.
