I still like the season, but some of the writing is just so weird.
Like having Tilly instead of Michael finish the race. I know its a throwback to when they practised running in the first season, but its a physical test and Michael is surely in better shape than Tilly. It would have been so easy to get around that by just making Michael drink the water because she can't take it anymore.
And finally we see why the doc keeps talking about his abuela every second scene he is in this season. She is now a hologram. I am guessing this is setting something up, new tech that reads your mind and makes a convincing hologram of someone you know. Surely that won't be abused.
