A Trio Of Eeveelution Sisters!

My character's mother would be an up and coming professional Pokemon trainer that's currently in the process of rising up through the ranks. Due to her career choice and being single, she finds herself traveling away from home for rather long periods of time meaning that before setting off she had to teach her son how to take care of himself while home alone from a rather young age. Though he's in his last year of high school and has been handling himself well enough for about two years now, his mother can't help but insistently worry about his well being.

This led to her coming up with an idea. She'd send some of her most trusted Pokemon that she had been raising back home to watch over her son on her behalf! This would consist of a trio of eeveelution sisters, a Vaporeon, a Jolteon, and a Flareon. My character is initially rather surprised by this decision, mostly due to not being informed until said Pokemon are already at his doorstep, though he finds that he doesn't object to the idea fairly quickly. What he didn't know though, was that his mother had informed her pokemon that his son was a rather sweet but shy sort of guy. She worried that he might have trouble making friends let alone finding a girlfriend. Thus, she gave them her permission (maybe even encouraged?) to help relieve him of any "stress or urges" he might be struggling with!
