If Rand didn't keep his emotions under control, he would've just widened his eyes about now at the mention of the words "keep" and "pet". Being kept as someone's pet meant very long term or even permanent, and those usually ended in death or insanity. The only reason he was still alive was because of no one keeping him around except for a particular female demon who had thought she had broken him for six months then had a fight with a siren over him. The siren ended up dead but the demon's host was too damaged for use so she left the hotel in search of a new host and Rand went back to the cages. The hunter certainly did not want to go through something like that again. Instead of replying to X, Rand faced the ceiling of the cage, laying still against the floor and braced his mind for more attacks.
