Interestingly I managed to discover a Huawei trojan that installed itself without me granting permission via a hotel router. It wasn't particularly well built back in the day which made it easy-ish to identify.

Tread carefully. You are in a relationship with someone who really is the new parent, and whilst you may act like a father figure, and have ambitions, don't get that confused with who's child it is. I only say this, because the last thing you need is resentment to build up because you might be able to do something that the real parent was not able to do.
I'm sure you have talked this all over with the parent, and like you say there were mitigating circumstances, but it is the other person who has the right to the decision-making. Just keep that in mind that's all.
