(Y/N) is graduating high school and is valedictorian. It's a surprise to her since the cons have been active. (Y/N) thought she barely passed to graduate high school. Between graduation rehearsal and writing the speech; (Y/N) is stressed out. Her boyfriend, Ratchet, is concerned, but she believes it's just stress and will pass until the day of graduation when disaster strikes.

It's a big moment in (Y/N)'s life; she's graduating high school end is the validation. She couldn't believe it, considering how busy the cons have kept her and her friends. She thought she didn't study enough for her exams. Her work isn't over yet. Between graduation rehearsal and writing the speech; (Y/N) is stressed. To the point, her boyfriend, Ratchet, is concerned.
"(Y/N), please let me do a check-up," Ratchet insists.
"I have no time, and I'm fine!" She snaps.
She packs up her stuff and walks away before Ratchet can scan her. However, it's not as effective as a full check-up.

Ratchet's concern increase as he finds (Y/N) asleep at her desk at three in the morning for five nights in a row. Once again, he insists on doing a check-up, and once again (Y/N) refuses. He can't do one as she sleeps either, regardless if he's seen her nude already.

He continues to watch (Y/N) with the feeling something is wrong, tempted to tell Prime so he can order her to let Ratchet do a check-up.

It's the day of the graduation ceremony. Unfortunately, both Fowler and Prime agree not to let the Autobots watch on-site, even though they have holoforms. With Raf's help, they're able to watch the ceremony from the base.
Ratchet helps (Y/N) get ready, noticing how tired she is.
"I couldn't sleep last night," she explains, but it's clear something — aside from nervousness— is wrong as she speaks.
Ratchet has to decide if he wants to ruin this day for his girl to do a check-up or not.
You're just paranoid. He tells himself. (Y/N) will be fine.
"Good luck, sweetspark," he says as the two hug and kiss.
I can't believe it. We met all of the kids when they just started high school, and now they're graduating. To watch the one I love on a big day is amazing — even if it's at the base. I'll plan a date for tonight.

"Finally, done with school!" Miko cheers.
"Not going to college?" Raf asks, resulting in a ''are you serious?' look from Miko.
Jack and (Y/N) laugh until (Y/N) has a coughing fit.
"Are you ok?" Jack asks.
"I'm fine."

The four friends didn't like they'd be separated due to their last names starting with different letters, but Jack didn't like not being by (Y/N). Like Ratchet, he felt like something is wrong.
Someone else notices there's something wrong with her, please. Jack hopes, knowing this would ruin (Y/N)'s day, but if her health is that had...

No one else notices something is off with (Y/N), and Jack watches (Y/N) walk onto the stage, uncertain if she is looking worse than twenty minutes ago or it's just him worrying too much.
"...we have reached a big point in our lives; adulthood, and while it's..."
(Y/N) ends up coughing, and jack swears he sees blood on her hand. He sees even his mom is concerned, but the principal and other adults on stage think it's normal coughing and will pass soon...until (Y/N) gasping for air could be heard before she collapses onto the stage.

Ratchet watches horrified. He quickly pages nurse Darby to bring (Y/N) to the base rather than the hospital — which is breaking the rules, but June knows how skilled Ratchet is as a medic. An ambulance couldn't get through to the stage anyway. June has the perfect opportunity to act like she called an ambulance and is taking (Y/N) to meet the ambulance, but she's wheeling the stretcher to her car. The kids manage to get through the crowd and join her. She needs their help to transport (Y/N) in her car safely but worries about what the kids will discover. There's no time to argue; she has Jack and Miko sit on the two ends of the back seats. Jack's lap is used as the pillow.
"Hold on to her," June instructs the kids as she and Raf get in.

The wait is agonizing for Ratchet. His holoform paces around for twenty minutes which to him feels like twenty hours. The kids help for the last time, getting (Y/N) on the stretcher before being told to stay with Bulkhead, Arcee, and Prime, who've already activated their holoforms to support the kids better.

"She's dead," June says in a sad tone, wishing she could have gotten here sooner.
"No, she's not!" Ratchet argues, "do you not give patients a fighting chance?!"
Rather than argue, June helps with drug administration as Ratchet does chest compressions. She sees fear on his face; Ratchet knows the risk he's taking even if they get (Y/N) back. A war going on in his mind; let her go or take the chance she'll be disabled, and how severe will it be?
Come on, (Y/N), I don't know what I'd do without you.
Ratchet tries for ten minutes; (Y/N) has been dead for thirty minutes.
"She's gone," Ratchet declares.
June leaves to give him a little time alone.

He moves a chair that's close by next to the bed, sits down, takes (Y/N)'s hand, and cries.
He's not ready to say goodbye, to have her body taken to the hospital's morgue.
Ratchet can't hear the beeping coming from the heart monitor through his crying. If he could, he'd probably think he's imagining what he wants to hear. He's unaware (Y/N) is back until he feels her hand move and her (E/C) eyes looking right at him.
"R-Ratchet?" She weakly says.
"(Y/N), I thought I lost you forever," he cries as he hugs her, lifting (Y/N) enough to get his arms around her. He kisses her as tears continue to roll down his face...

June arranges for (Y/N) to stay at the base while she recovers from what happened. Ratchet's tests conclude (Y/N) was way too stressed, and refusing to take breaks added to the strain on her heart. Thankfully, not enough to cause damage resulting in (Y/N) no longer able to be as active as she is or need a heart transplant.
June and the kids also find out the graduation ceremony ceased after what happened and will happen in two weeks.
"Now you're prepared and can rest," Ratchet tells (Y/N) after telling her the good news, "and Prime agreed to let us come."
(Y/N) believes Ratchet is too worried to watch from the base, and the others didn't like not being part of the crowd to celebrate with their friends right there rather than waiting until they returned to the base.
