I'm kinda wondering if he is waiting for or alread

I'm kinda wondering if he is waiting for or already knows the 2 week test results on his mother in law. He did say she's had 2 injections. That would suggest 2 weeks. I believe they do a test 2 weeks in then every 3 weeks after that. Would make sense since I believe they pr'd the 5 week and 8 week results of the first patient.
