Ezekiel and zeke used to getting beaten up and experimented on harshly by other experiment doctors, their previous care takers would harass then and beat then up, they was emotionless until stone came into their life

Stone was his care taker, strangely stone was nice and would take the experiments gentle to not hurt them.

Ezekiel and zeke slowly started to fall for him...their emotions came back when stone was there

(Note: Ezekiel and zeke have tentacles and they are 6'4, Stone is 5'8 and doesn't like being harsh to Ezekiel and zeke)
