Lamb to the slaughter

Yeah? That's great. Thanks though, I'd rather not get killed.

Name— Marie Alain Snape

Gender— Female

General Appearance— She has her mother's nut brown hair and her father's dark eyes. She is short and ungainly, and not too well endowed in the chest region.

Personality— What she lacks in looks she makes up for in personality. Her clumsiness and social awkwardness would be annoying if she was not so adorable about it; as it is, she has her own sort of charm. She likes to help people and will go out of her way to do so, though she is sometimes less-than-politely turned down due to the 

Special Talents— Making people smile and laugh, helping people appreciate the small things in life.

Who they like better— Her mother, because she tends to understand her problems better. She loves her daddy, and is quite a daddy's girl, but she'd still pick her mother over her dad if she had to.

Who they take after more— Emmeline, most definitely Emmeline. Though she has some of Severus' genius, she is like her mother to a greater degree. Sweet and awkward.

Personal headcanon(s)— Sorted into Hufflepuff like her mother, she doesn't struggle in school (except socially). The family spends a lot of time together, going on excursions or just sitting at home. People think she and her father have eerily similar laughs.

Faceclaim— Alison Brie

Name— Landon Remus Snape (Severus did not like Lily's suggestion for their son's middle name, but eventually relented because her friend had been nicer than the rest of his gang.)

Gender— Male

General Appearance— Landon inherited his father’s height and lankiness, as well as his dark hair. He has hazel/green eyes, and a rather rosy complexion, especially compared to his father. 

Personality— Landon is, above all things, honest. He never really learned how to lie. He speaks his mind when he thinks it’s important to do so, and keeps quiet when need be. His brother calls him a walking library, because “encycolopedia doesn’t even begin to cover it”. He has a photographic memory and will often interject facts into conversation when he finds them relevant. 

Special Talents— Aside from his genius in magic, Landon has a talent for taking care of children. 

Who they like better— Landon loves both his parents in different ways, for different reasons. If he had to choose, though, he’d probably say his mother.

Who they take after more— Landon is a pretty even mixture of Severus’ introversion and Lily’s intensity. He is a quieter version of Lily and a less serious version of Severus. He leans toward his father just the tiniest bit though.

Personal headcanon(s)— Landon is a balancer of the family; he is a voice for his older sister and he mellows his younger brother. He is the brilliant one, the modest one; he helps his sister in school and tries to teach his brother how to not seem so arrogant. He is a Ravenclaw, though he could have also done well in Hufflepuff, his mother thinks.

Faceclaim— Noah Silver (but I couldn’t find a good gif so this is someone random)

Name— Leif Marcus Snape (Marcus is a family name on Lily's side, and they both just sort of liked the name Leif, Severus in particular.)

Gender— Male

General Appearance— Ginger and green eyed like his mother, Leif is handsome and he knows it. He has freckled skin and an athletic physique, and an ever present smirk. He has his father's height.

Personality— Since he was a toddler, he has always been a ladies man. He is a flirt to the highest degree. He is constantly getting into mischief, pulling pranks or simply finding himself in odd situations, though he rarely gets in trouble. He attributes this to his charm and good looks but his brother calls it luck. He's the most expressive, exuberant one in the family.

Special Talents— The skill he brags about most is his fantastically large mouth and how much food he can stuff in it. His brother finds this obnoxious and slightly obscene, and wishes Leif would tell people about his talent for Transfiguration instead.

Who they like better— He loves both his parents dearly, and would never tell anyone, but he aspires to be more like his father. His father is his hero, though he tells people he wants to be exactly like one Rubeus Hagrid.

Who they take after more— Lily. He was sorted into Gryffindor like she was, and has her same skill for seeing the best in others. He also inherited her charm and wit; his ability to make up excuses and stories and retorts on the spot come from her.

Personal headcanon(s)— Leif is the third child, born 17 minutes after his twin brother, and he takes advantage of being the baby of the family. He's also got a fat cat called Arnold who he often blames for the mischief he makes.
