BD-1 borbles a greeting at the Nightsister, turning from his observation of Cal's work to instead watch as Merrin has a look around. There's a few repaired lanterns and things out. There's also a piece of equipment that looks slightly different from the Agrii's simpler styles. Beside it is a headset. So the music of ancient Coruscant and the core worlds at the time may not be anything he was familiar with, but Cal had still missed music enough not to pass up on an opportunity.

It isn't long before Cal's powered down his arc-welder and pulled his goggles down. He doesn't seem surprised to find Merrin there, but then he hadn't been so lost in his work that he hadn't sensed her arrival.

"Hey Merrin." It's still just a little strange to him to be greeting her so casually, but not so strange that he can't offer a smile. "How's it been?" Thankfully things have been pretty calm around the city since their return.
