The umbreon has recently been caught and was brought home by a trainer, this trainer is passive and usually leaves his pokemon at home instead of battles. At the house is a sylveon that usually trues to help him adjust to living there but she always gets too nervous and she usually never finishes her words, she's nervous because of his sheath. Since he was recently a wild pokemon he never learned to keep it hidden in his fur. She doesn't really mind tho, she kinda likes umbreons already...
