Fusion nodes deleted

I had a clip in the timeline and went into Fusion and created some speed changes and added a title. When I went back to the edit page I decided I wanted to get rid of the effects and not have any effects on this clip. So I went back into Fusion and deleted all the nodes including the MediaOut node. Oops. Now when I go back to the edit page the clip is still in the timeline but it is not visible in the viewer, though I can hear the audio. I know I could just recut the clip back into the timeline but is there another way to view the clip that is already in the timeline?
And what is the best way to get rid of effect changes in Fusion if I just want to go back to the clip as it was originally? Thanks--
