Little Details Not Noticed Before

When Joe and Alice are in the museum, Alice gets tired, takes her shoe off, then hops on a flat edge of a statue, I believe. (Smart move considering the glaring height difference between Garland and Walker). Joe joins in sitting on the statue.

At one point, both Alice and Joe hop down. The natural assumption is that they are ready to go on their way. However, a guard passes by them soon after. Immediately afterward, they hop back on the statue, lol!

In all the times I had seen this movie, I never noticed these details! Probably because in all this time, they NEVER halted their conversation- not once! The two actors/characters naturally followed each other's rhythms and kept up with their actions without missing a beat on their dialogue!

Anyone noticed this or any other interesting details?
