The question is... is Eugene really still just a coward? Has he been marginalised and mocked by Rick & co to the extent that he really does feel like he has found "his place" with the Saviors?

OR... is he simply smarter than Daryl... who I said as soon as Negan took him, should hold out for a while and then pretend to be "broken", become a Savior, get on the inside and help to destroy them from there. Is that Eugene's long term plan? Get close to Negan for now, keep his head down, wait for the war to come and then be in position to make a difference from the inside? Hmmm.
