Did You Know?


Before mounting his defense against the T-Rex bones, Ralph says, "Warning, fists in the pipeline are larger than they appear." Similarly, in the original Jurassic Park, when a full-fleshed T-Rex was pursuing a Jeep, the dinosaur appeared in the exterior rear view mirror of the Jeep. The mirror had the warning "Objects in the mirror may be closer than they appear." See more »

[first lines]
Ralph Dibny: Good old CCTA, bus number 405, where I was gifted with pretty much the best powers ever. If it wasn't for this old girl, I'd still have to leave the couch when I need to use the bathroom, you know, because I can...
Barry Allen: Yes, I know.

Joe did what Wally West couldn't do (earlier episode), but the director finally showed her direction using Dibney in a meaningful way. My ratings (based on what I marked on IMDb): Season 1: 200/23 = 8.69 Season 2: 193/23= 8.23; Season 3: 188/23= 8.17; and Season 4: 119/18= 6.61 (This episode = 8/10)
