This here is Gagnesh Mritue, Anala Mritue's 15 year old son, born before she moved out of India. Despite not being Alistair's biological son, he loves Gagnesh like he was his own flesh and blood.
Gagnesh himself looks up to Alistair quite a bit, wanting to be a monster hunter just like him after college. He's quite intrepid and bold himself, matter of fact he's even gone on plenty of adventures with his own friends throughout Hetelville.
Adventures I'll be telling you more about later...
