On The Flash Season 1 Episode 3 when another new metahuman starts killing important city officials, Joe realizes that they are going to need the help of STAR Labs, not only to find The Mist but to figure out a way to house all of these super criminals so it's not necessary to execute them all.

Caitlin Snow is profoundly touched when she learns they will be using the particle accelerator to as a prison, not even because of the nearness of the criminals, but because that is the last place her fiance Ronnie Raymond was seen alive. 

Barry notices this hesitation in Caitlin and also knows that she might want to talk about someone who meant so much to her. He offers her an opportunity to open up and we learn about her relationship with Ronnie.

Harrison Wells becomes even more mysterious as we learn what he knew ahead of time and the chances he took with the particle accelerator, seemingly to achieve specific results. Just who is the guy?

Joe wants to reopen the case against Henry Allen and he and Barry will do it together. When Joe goes to see Henry for the first time in years, his life is in danger. Who will help him out?
