Earlier that day, when Harker and Joan were still in the Kokoro to Shinzou antique shop, Roland had to take care of some matters for proceedings of Felix's re-trial. They're running out of time.
Soon, there would be an examination of evidence, and they need to gain that evidence and witnesses to prove his innocence. Not only that, but they needed witnesses and testimonies to prove it.
Once Harker was done with Galeas, Roland informed him and Joan about this. They would also have to serve as a witness in case they truly uncovered something big.
"I'm fine with that." Harker said. "I'd probably be your best bet to stop any foul play. How about you, Joan?"
Joan shrugged. "Never really liked court trials and never been to a proper one before… Not under the US Constitution, that is. But as long as you help me with the prep work, I'm all good."
