See, he has some good points!
....During the secret chamber task they have to get into a tunnel quickly to get back to the exhibit area. When the buzzer goes, Luke A helps Luke S unzip the back of his costume then dives in without a glance at Deana who is struggling with her costume. Adam has long gone, the first to make the dash. Luke S goes over to her and helps her with her boots then stand back and lets her go before him.
In another clip, Luke A, Adam are again first to go while Luke S waits until first Ashleigh, then Deana are into the tunnel before he goes. He risked being the one to fail both times.
This throws some light IMO on why he doesn't respond in any way aggressively to Deana's taunts and why Conor 'sucked him in'. He has good manners and is at heart a good person who isn't just out for himself. It proves he certainly isn't vengeful.
I like him a lot better than I used to.
