In the film Triangle we learn at the very end of the film, that the Jess we meet in the beginning already went through the loop (maybe even all of them). She remembers what happens on the liner, and she must remember that her main goal was to stop the entire crew from stepping onto the liner.
When the moment comes when the crew wants to be "rescued" by the liner, why didn't she try to stop them? She hesitates, but doesn't act on it. Why?
