first of all the way you describe your charries had me laaauugghhhinggggg lol

okay so
my viking actually needs a partner in crime, a mean friend just like him. he and frost could possibly link up for a job and thats how it all starts and BAM maybe not friends but mutuals who take delight in evilness.

or or
send frost to my lil dove of a girl, idk i feel that would be interesting to see how he takes her personality and how she takes his. cause she is literally his opposite. but she isn't weak.

or or
send dorian to her, she is old fashioned and "royal" and regal and stuff they might get along well.

its up to you :3
