When Giix gets to 65N95E10Z, a large hand of force appears (CL check 29) and tries to push Giix back. It does not succeed (16 vs. 25 bull rush), but Giix cannot fly towards her opponent because the hand is in the way. Giix does not stall (26 Ref save) from the sudden stop and she does have movement remaining, as long as it is not towards Ari.
