These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Time Tunnel
Padding: One episode ends with a brief sequence of Tony being successfully brought back to the Time Tunnel base, but ten years too early, before he came on the project. It's clearly the result of the script coming in short.
Tearjerker: From "The Day the Sky Fell In": Tony witnessing his father's death at Pearl Harbor, and telling him the truth about who he is. His father actually believes him, and dies happy knowing that his son survived the attack.
