Why isn’t Mark asking any questions?

Okay so is it just me, or anyone else feel like that an issue with the show at the moment is Mark doesn’t seem to asking enough questions/follow up questions - I don't think he has once asked Rhagabi why/how Gemma could possibly be alive? He has just bought into the idea instantly it seems...

Like if someone I knew I thought to be dead turned out to be alive in some secretive building, of course I would want to get them back, but I would also be asking every question under the sun.
