That sticker had come from Cisco surprising her with a pack of Frozen stickers shortly after they started training on how to use her abilities. He managed to convince her to stock at least that one in the overhead light. However, if some people looked closely, there was an Olaf sticker hidden somewhere. Caitlin has yet to find it and swears that when she does, she would ice block all of his tools.

For now, she lets the remnant take the slow breaths, watching as his eye flicks over everything before it finally closes. She breathes a sigh of relief and checks on his vitals one more time before meeting with everyone else to debrief what happened.

When the question comes up with what to do with the surviving remnant, Caitlin argues the case that he should have his own life. Somehow. Maybe pass as Barry's twin or family member for the time being. Then they could resettle him somewhere. According to Cisco, it worked for the Tenth Doctor. She just needs to make a few phone calls and reach out through her contacts.

If she could find a home for Magenta, then she could find a life for the remnant.

When he wakes up, she'll still be sitting at his bedside, sipping coffee and working away at her tablet for a better speedster anesthetic formula.
