Slow affecting a character being advanced by another character

[Zetan]

In this topic it was clarified that a character advancing itself using superpowers and tactics cards with the slow condition will only move short: 

 

However, does this same logic apply to another character advancing them? For example, if Cassandra Nova uses Mind Possession on a character with the slow condition, does Cassandra advance them S or does she use their normal Speed?

[Negoldar]

Yes, Slow applies.
