I love that they already have it & you can see how protective & caing he is for them in some of those gifs
. Its probably the British accent but I feel he's a mix of Giles (from Buffy) & Leo (from the original Charmed). He's not necessarily a love interest (at this point anyway
), he's looking after them, & can be a fatherly or brotherly figure for them if needed. Then they're all coming together & really caring about each other as if they're all a family even early on which I feel mirrors Buffy more than Charmed as the bond there came later when Leo was more a part of the show/becomes a main character
