Seems like it might work?
After demonstrating hostility and vigilance, not only did Number 3 not act directly, but instead threw an olive branch towards her, the Pure White Holy Mother couldn't help but feel a hint of happiness in her heart.
According to Omnia Cicada's analysis of Number 3, her compatriot is insidious, treacherous, suspicious, and highly alert, holding a strong distrust towards anyone who approaches. Showing goodwill may not necessarily guarantee favor, but it will certainly be met with repeated suspicion and endless probing.
But if acting counter-intuitively, by showing resistance and vigilance prior to Number 3, it would greatly weaken his guard and indirectly bring the two closer.
As long as she maintains her current persona as an impeccable "True Holy Mother," then the hypocritical and ambitious Number 3 will proactively limit probing to demonstrate sincerity in drawing her in, which provides the best opportunity to approach him!
