Funny exterior with a soft core.Fun theatre watch.

I don’t understand the plot, can you please explain?

The goober. The countries want it to control them. Ethan wants it so we can destroy the entity. Why does Gabriel(the entity) want it ?

Why can’t the entity nuke Rome when two parts of the key are on Rome(or Venice) and be done with it.

Ona side note,am all knowing entity can’t get to its own source code or recreate it ? I have a feeling that the entity wants Ethan to get the key for some unknown reason.
