Using Turnover on a tile containing both your ally and a solsphere tile will behave as if you targeted an enemy, hitting and moving both.
Mad Chop will also hit an ally in the same situation.

Shinken, Execute, Round Trip, Retreating Swipe, Thousand Stab, and Incise all behave normally, ignoring any allies in the tile.

(Also, incidental but I only discovered this while testing THIS because I don't use it - Mad Chop only seems to do the star-shaped burst if it hits a solsphere on its own - if it hits an enemy + solsphere, it plays the impact effect on the tile but does no additional damage and does not spread any further. Can turn this into its own thread for tracking.)
