For a small stretch of time, the only noise being generated near their table is the sound of impact from Lucas and Miss Chievous kicking each other's chairs repeatedly, due to reaching a lull in the conversation.
Understanding that Miss Calculated might take a while to prepare 23 and separate it from the restaurant's hive mind network interlinking its service bots, Miss Masher opts to resume storytime once more.
As she is continuing mid-story for a scene that makes absolutely no sense out of context, Lucas has mostly tuned her out for now.
'...How come Chi's stayin' invisible still? Doesn't it use some sorta supe-energy or somethin'?'
[She wasn't joking before when she said she had a surprise for you. If she were to release her power on herself, she'd still need to maintain it on the contents of her arms until she was ready for the reveal, which I assume won't be until everyone is outside. Were she visible, it would be obvious that she's carrying something.]
