You met Luke at the park casually, you both were on a walk with your dogs, let's just say that they were match makers to their humans while they were busy being each other's best friend
Once that you met on the park for second time, you exchanged numbers and met each other slowly, taking your own times to know each other perfectly while getting more and more serious with the relationship
Luke, tired of the team teasing him about the relationship he had with you made the decision of letting the team meet you, even if he feared what would Garcia told you just to mess with him. You ended up loving the team and the team ended up loving you, especially Penelope, to Luke's big dismay
After a few years, Luke asked you to move with him, then the ring came and finally, the child
Now you are at the hospital, just having the little ball of hair on your arms as Luke looked at the girl with astonishment and a big amount of proudness for the both of you when the team came in. With the great Penelope Garcia openning the door
"The aunts, uncles and the grandpa are here" she said with joy, making you and your husband laugh as she ran to you "How are you, my Godess of sweetness? Was it to rough?" she asked after hugging you before looking at Luke with an indignated glance, making you laugh and your husband make a face "Did you met her expectations?" Garcia asked him before looking at the baby on your arms "Oh my... that's her? She's so small and huggable and..." Penelope pauses, overwhelmed with the newborn "... And... Can I hold her?" she finishes the ramble as you nod and JJ moves to hug you next as Rossi congratulated Luke and joked about being the rich grandfather, while Spencer, Matt, Tara and Emily stand close with a smile as they wait for their turn.
