Ok,
Bartholomew looks over the side to see the dragon, assuming I do (this should also let us know if the gish is around, if he chooses to counter):
Hypnotic pattern on the dragon and rider (150' range): If it goes off, DC 18 WIS save at disadvantage.
Edit: 120' range on hypnotic pattern - but should make no difference.
