Lex is busily conversing amid a group when two of the partygoers start talking amongst themselves, giving him a moment to pause and survey the room for himself. He catches Adrian looking at him and he notes that it's not for the first time.

Looking through the crowd and making eye contact with Adrian, he raises his glass in return, looking pleased with how well the party is going. He looks over the rim as he drinks before resuming conversation. While speaking Lex turns his head again, catching Adrian's glance and using a hand gesture not meant for his audience (though that's what it would look like from a passing glance) to motion toward an area less crowded.
