okay, cool! she can definitely be a pseudo sibling for them. their mom really pressured them to be successful which the two older siblings are and kelsie and eben are fairly successful with kelsie going into nursing and eben being a paramedic although mom would rather they be surgeons or doctors of some sort. i just peeked at her info and i love that she's in the medical field too! kelsie isn't close with her sister because of the age difference and she's kind of more of a mother figure or she tried to be since there's a 16 year age gap but maybe penny is more of a sister to her?
