We watch "World Enough and Time" (Season 10, Episode 11) where Doctor Who, Thing One, and the other one maintain at least three feet of distance so that they don’t accidentally remove an innocent's major arteries. Whilst said life protectoring is occurring, Doctor Who (aka Missy) gets in touch with her masculine side, Thing One (aka Nardole) mostly kills time 'til episode next, and the other one (aka Bill) becomes a fan of watching the Doctor on TV. Companions... they're just like us.
