Jack McGarrett had gone inside in order to get another beer for both himself and Chin when he noticed the unfamiliar car parked beside his home. He immediately became alert, angry at whomever dared to try interfere on Grace's birthday. Then he saw him, standing in the shadows of a tree, watching Danny and Grace the closest.

The man was in a suit and loafers, his tie fluttering in the afternoon breeze. He studied the man as he suddenly seemed incredibly angry and then—he just deflated. Sad and defeated, yet a morosely understanding smile was on his face.

Taking in the emotions the man was exuding he studied the man even closer and was startled to realize that the man watching from the shadows was Danny's father. He had the same jaw line and nose, the same light colored hair curly hair. He was of similar height and, though not as defined, build as his son. The only difference between the two was how happy Danny seemed to be and the saudade air that surrounded his father.

With a sigh he quietly walked out to the man who appeared to be getting ready to leave his children without informing them he was there.

"You know, it's never too late to make amends. It might not be perfect, not like it would have been if you had been there for every important part of his life, but you'll still be a part of it."

Mathew Williams whirled around in shock, not having realized someone was behind him, and faced the man who had spoken, spooked not only by his presence but his words too, they hit home painfully accurately.

"I—uh, Mathew Williams, Daniel's Father." Jack nodded at the man, "I figured. You two look a lot alike. I'm Jack, Steve's Dad. He's the one who's tossing Gracie into the surf."

They both looked at where their children were, Danny taking pictures as Steve and Grace splashed at each other until Mary ran up and stole the camera and pushed Danny in as well. The two in the water laughed as Danny sat up and yelled at Mary before he got up and tackled Steve into the water himself, Grace jumping into the fray and leaving them all laughing uncontrollably.

Mathew's face showed how he was feeling as he fell back into forlorn nostalgia, "I hadn't realized, you know, how much I'd let my family stray from my sole purpose in life until I came back this morning. There on the calendar in the kitchen screamed at me that today was my youngest's birthday and there on the counter were notes scribbled in my eldest's handwriting what all had to be done to get ready for today, who was bringing what and what needed to be prepared."

Jack was quiet for a moment, "I'll admit that I've not been exactly Father of the Year for the past few years running myself." Mathew looked at the other man, not saying anything, just knowing he had to say it in his own time, "When my wife was murdered I practically abandoned Steve and Mary, I immersed myself in finding her killer so much. Your son," Jack couldn't withhold the laugh, "He's very in your face when he thinks something is wrong. He and Grace somehow managed to not only get Steve and Mary to get along and smile more but somehow broke me away from my obsession, at least so much as that it no longer has distracted me from the family I have left."

Mathew grinned wryly at that, "Yes, he's always had a very accurate view of what is right and wrong, morally at least. When I first got the promotion in my job that brought me here, he flat out told me he was coming with and I couldn't stop him if I had wanted too. He's very stubborn when he wants to be." The grin faded, "Because of that stubbornness, however, I'm not sure he'll ever quite forgive me for what I've done to our family."

Jack watched his kids and the ones that have somehow become his kids without ever consulting him, "I think he's a lot more forgiving than you think. You might not be close, but he'll let you be part of his life, and eventually you'll get there. Come on, the least you can do is tell her Happy Birthday."

Bright blue eyes, so much like the one's he'd gotten to know these past months, stared at him before he straightened his shoulders and nodded.

Looks like he added another person to their odd family.
