The last thing Tobias remembered before showing up in the park was Jake giving Rachel the signal. On the other ship and all on her own. He didn't have to see what happened to know what was about to happen. The only small relief about this place was that he didn't have to live with seeing it.
Even though he was talking to her it didn't set in that it was her until she was standing there. He stood there staring at her for a moment before he felt those arms around him. He let out a breath of relief and his arms lifted around her. His head buried into her shoulder as he squeezed her arms around her gently.
