HC,
Always with the either/or.....what about shades of gray sometime?
Like the Crew did what they did as normal, thought not much of it, did not think the Pax sensed something out of the ordinary happened, never even gave a thought a quick mention would be useful, the Pax were not fussed, did not quiz the Crew on their way out, and after thinking about it the OP though to ask here.
You reckon there is "innocence" all the way around here.....and nothing "sinister"is involved in any of this?
Have another cup of Tea.....relax.....everything is okay.
