Perhaps there is no permanent cure for Autobot but if we can 'reset' the timer on his body back to what it was in peak of first age then it's victory anyway. We can puzzle then next millenia how permanently cure him then.<br/><br/>As SWILIH cure charms focus specifically 'return things as they were' it is valid route. Considering the fact that no twilight solar had access to SWILIH charms (unless being akuma and SWILIH had no plans helping Autobot despite she may be best person to do it).
