Aw snap, though if Morii was smart she wouldn't harm Houjou and just use her as an outfit to keep tabs on Mario and guide him along then worse comes to worse she could always engineer something where she has to save Mario and showcase how much he truly needs her while making Houjou seem detrimental to him in multiple ways. Putting her at risk or blatantly showing off that she can puppet her along will just create more distance between her and Mario which is something she should want to avoid.
