Click the link for a quickflash of Uranus ~>  freak flags.
Again, from the archives (Pluto is linked in the post below).

Uranus is square Pluto from South Node (opposite North Node) while Pluto squares all three.  (Uranus and both nodes.)

Squares aka inner friction, obstacles and tension between two energies that can be more powerful than a trine if solved because you have to work so hard to fix it !
