The character of the thing becomes apparent in this Act - bullying and very flirtacious. The Thing has essentially united with the user, and treats him very possessively. This should be strong enough to set up a feeling that that user would like to get away.
The Thing will suggest a mode of communication - two pushes of the PLEASURE button for yes, three for no. In this Act the Thing shows the user around the domain they find themselves in. The conrol lies with the Thing to suggest things to do and see, the user can only agree or disagree.
There should be adventures here, games and surprises. Although the Thing is over-bearing, it is also the source of understanding the strangeness all around. The Thing's actions should help or save the user in tight spots
