When a character is riding their mount, which has significantly weaker stats in this case (not that it honestly matters for the general question) and they are charging an enemy, and one of the enemies allies casts grease under the mount the mount is the one that would role its saving throw. Failure lands the mount as well as the character prone, is how I am reading the rules anyway. I ask this so as to get others thoughts on other actions that could possibly happen under the rules before the horse actually roles its saving throw and falls to the ground. These actions would be allowing the character riding the mount to role a ride check as a swift action, thus having the horse either dodge or jump over the grease spell. I wouldn`t normally allow this if its not a character that has a bond with their mount and doesn`t have any mounted feats, for in this case the character has multiple. I will include the stats for both the rider and the mount below.

In this case it involves an NPC, but in another case involving a PC which had wings I have allowed them a fly check as an immediate action to catch themselves from being thrown into lava before they had to role a savings throw.
So basically my questions is, am I massaging the rules to much or are the rules actually made to do things such as these
