Biography
Ronnie was at S.T.A.R. Labs for moral support for Caitlin on the night of the particle accelerator's switching on. After it was switched on, it worked for a few minutes, before it began to malfunction. Being the structural engineer of it, Ronnie went down to the core chamber of the particle accelerator, along with Cisco Ramon, to shut it down. He requested that if he wasn't back within two minutes, to lock the doors to keep the rest of them safe. While in the core chamber, Ronnie redirected the accelerator's magnets, causing any potential explosion to direct upwards rather than outwards. He came back to the door, which had been closed by Cisco, and contacted him via walkie talkie. As Cisco set the particle parameters to align with the upward explosion, Caitlin talked to him, urging him to find another way out. However, he explained that the only way out, the door between them, had to stay shut in order to keep them safe. He began to speak, though didn't finish his sentence, presumably stopped by the explosion of particles within the chamber.
