I grinned like an idiot throughout the first episode because of all the Voyager callbacks but I got the biggest laugh in the second episode when Boimler goes to his new quaters and the room is bright red because of the glowing nacelle. I had to pause because I was laughing so much. For the past ~30 years I always wondered what crew quarters which face towards the nacelles were like. Thank you, Lower Decks.
Shax could have just told him about the built-in filters on the windows, but he secretly wanted someone to hear his holodeck "adventures" with T'Ana. It was a cry for help.
