Sadie did not want to leave her daughter behind, nor did she want to abandon Mina, but it was the only thing she could think of in the moment. Troy followed Ren on social media, so he knew the man was in the country, and they had it on good authority that he never believed they were dead. Claire told them that before and after the man was released from the institution, he searched for them for months before Drew got involved and sent him to another country. The end goal was not just to prove that they were alive, but he also wanted to prove to Mina that he did not kill them.
In hindsight, the pair could see that framing Ren for their accident was a little too cruel, but they needed to convince Mina that they were dead because they worried she would find them and lead Ren to where they were hiding. Now, in the middle of an event where Mina needed them, Troy's secondary contact within the family warned them that his mother was being aggressively searched for.
