I will never believe ‘banging on the glass’ had anything at all to do with what happened on that ship. In the picture the family posted as an example, you can see that Chloe is reacting to something that just happened in front of her. It’s probably as innocent as what I’ve seen happen a hundred times at a rink - her brother probably skated by in warm-ups and tapped on the glass with his stick in front of his little sister - maybe saying hi or even making a silly face. She was REACTING to her big brother. She wasn’t just banging on glass cause it was there. The look on her face shows the joy at seeing her brother and just starting to turn to share with her parents. Just my opinion.
