Author's Note: This is just an alternate ending that I felt like writing. It takes place after the last flashback.
Samantha had stopped walking. She looked around, finding herself standing in the middle of a park. She was also alone. She walked towards a nearby bench and sat down. Sam leaned back and closed her eyes. Memories came rushing back so strong that Sam gasped, opening her eyes. Tears flooded her eyes and emotions threatened to choke her.
She brought her knees up to her chest and hugged them. It had been two weeks since he died and during those weeks, she kept to herself. Sam missed Martin. She missed having him around to confide in, missed his endless hugs and kisses, his bright smile and laughter brightening her day. She even missed his teasing about her driving. But mostly she missed how he made her feel whenever he was around. Even her apartment seemed brighter with him around. Now, Sam couldn't even go home. She had nowhere to go.
A tear fell and another followed. Sam began crying uncontrollably. The tears kept falling; Sam could stop them. Sam sat on the bench all by herself, crying, knowing she'll never stop crying.

A few yards away, Danny stood behind some trees as he watched his friend cry. It wretched his heart to see her like this but he knew Sam had to go through her pain alone. So Danny stood watching as Samantha cried over Martin, her lost love and his lost friend.
I don't know if it came out exactly how I had it in my head but I figured it was sad enough for me. Plez RR!
