Was this his aim from the beginning?
No. It hadn't been his plan from the beginning. However, that thought grew after they left the bookshop.
Michael thought about it when they were in the cab. He looked at the maternity book and wondered. Someone who only moved with money. Someone who was very well versed in the arts of killing. And someone who understood a female's pregnancy perfectly and could tell if there was something wrong with them with a simple glance. That person was Doctor Ro.
If he had him by his side, then he wouldn't have much to worry about.
It was a benefit he didn't want to give up.
As such, he would cover up the fact that he had colluded with the Lycans to kidnap him all for money and save him from Noah's wrath.
Of course, if Noah found out that Doctor Ro had colluded with the Lycans, he wouldn't just hand over the tripled sum, he might even hand Doctor Ro's head to him on his hand.
That would be his funeral.
