Obi-Wan is about to take another sip of tea when Ren's question causes him to pause. He then lowers the cup again with a slight frown, thinking that over.

"I highly doubt they would approve allowing you access to your lightsaber just yet."

Though it wasn't for lack of Obi-Wan's belief that Kylo Ren has learned his lesson, but rather everyone else doesn't trust him.

"But I will see what I can do."

Maybe he can at least get an idea of when they would allow it.
