Hades may be Lord of the Underworld, but He's not omniscient. Rumple probably hid somewhere and set protection against the Lord of the UW (not realizing the Regina now has a strong vested interest in protecting Zelena). And Even Hades knows it probably takes more than one person to tackle the Dark One. Finally, he has a bargaining chip, in that he can remove everyone's names (well, except Killian) from the various headstones.

Prediction, Rumple and Pan last 5 minutes, then Pan goes Bye Bye into the river. Cruella tries to get in Killian and Emma's way, and Emma finishes the Job she started in Season 4 (hopefully with a good B-Slap to repay the one she received last week), about 3/4 of the way through the episide. And when Hades is freed from his servitude in the UW by TLK from Zelena, The Blind Witch is promoted to the new Queen of the UW. (jk on the last one).
