Synopsis

The player simultaneously treats the Miner, Hailey, Logan, and the Samurai through their respective heart issues, as a dusty fog rolls through. The level starts with the Miner being treated, with Hailey coming in shortly after, followed up by Logan, and finally, the Samurai is treated independently before being combined with the other three patients, with all four being treated at the same time. After the level, the Miner thanks the player for their treatment of him once again, and asks for them for advice, before soon finding out that the intern is unable to talk through their screen. He then remarks that he'll try to seek medical help whenever he can. Ian then contacts the player from the hospital, asking for their help in treating Mrs. Stevenson and her birds.

Transcript

	Whoever you are out there, you saved my tail twice.
	Wish I could thank you properly.
	Truth be told, it's been a while since I've been to the doctor.
	Maybe I've been pushin' myself to my limit...what should I do, doc?
	...
	...anything I should eat different, or...do I need to step away from work for a while?
	...
	Guess you can't talk, huh?
	I'm no medic. I'll have to find someone who can help me out. Thanks for tryin'.
	I'll just hang tight and hope for the best.
	H-hey. It's Ian again.
	Can you shift your focus back to the hospital for a second?
	M-Mrs Stevenson says she needs help with her, uh...birds?
	With Paige at home and Edega making the rounds, everything needs to be p-perfect.
	Let's sort these patients out, and then you can continue on with your work on the train.

	Hey, wanna hear a story?
	I'll take your silence as a "Yes, please."
	That Ada Paige lady is pretty cool.
	We don't talk much. I mostly just keep to myself.
	But one time...she was working with this family.
	The father was recovering from a heart attack.
	He was in pretty poor health, so everything seemed a lil' touch-and-go for a while.
	His wife and four kids kept visiting. The youngest son kept running around the halls, getting in our way.
	It was a huge pain-in-the-neck, for me. Having a big family in here, on top of everything else.
	Paige ignored the distractions. She worked hard, I could tell.
	She not only operated the best she could, but also went the extra mile in talking to the kids.
	The wife was so scared, she didn't know what to do without her husband to help.
	It felt like we were all playing babysitter for her kids during that time, but Paige especially.
	In the end, Piage was able to pull off whatever fancy operation she was doing in the guy's chest.
	It was a success, he ended up totally fine.
	And get this, when the family was celebrating, ready to leave and go home...
	I saw Paige enter the broom closet and grab a box. I had no idea what it was.
	It turned out she had brought the oldest child a birthday present.
	His birthday was the day after his dad had the heart attack.
	Paige said "Each Birthday you have only comes once...
	...I'm sorry you had to spend it stuck in this place. I hope this present makes up for it."
	The mother and father were like "thank you thank you thank you."
	It was so sweet, but I just didn't get it. Why did she bother to do it?
	She's treated at least a hundred patients before. People come in and out of here all the time.
	Why would she waste the time finding a birthday present?
	Maybe it's just because she's young. She's still pretty new to this.
	Maybe she'll realise soon that there's no time for sentimental stuff like that.
	But either way...every time I pass her in the hall, I think about those kids.

History

• Upon release, this level used employed a heavier use of visual effects in an attempt to further challenge the player. The section of the screen containing the first three patients would notably flip upside down, before flipping itself horizontally. It would repeat this sequence once more before the level ended. This screen-flipping effect would be removed in a later update to reduce the difficulty for new players.
• Upon release, the level featured Richard Hugh as the third treatable patient; Richard is known to incorporate fast Classic Beats, and was presumably present to match said heartbeat in the level. However, in an update which came after the level's previous difficulty update, Richard would be replaced by Logan. The heartbeat, and gameplay itself, was left unchanged. This change may have been made for several reasons. It might have been in an attempt to follow the story and theming better, as Logan is the love interest of Hailey, who can be assumed to have been missing her for the time that she spent away from the hospital. Additionally, Richard Hugh is a character who views the Middlesea Hospital with distaste, making his presence in the level somewhat unfitting. Finally, the heartbeat in question lacked any Row Xs, which is a characteristic feature of Richard's heartbeat lines.
• In the Act 5 update, this level received several changes.

• Along with its Night Shift counterpart, this level received a visual change to more heavily include the use of fog. The background itself was also changed, featuring slightly different background fog and a different shade of blue for the background sky.
• The screen's rotation effect has been heavily toned down, now featuring a much more tame version of it, with less frequency than was present in prior versions.
• Logan and his heartbeat line will temporarily move out of view when the Samurai is being introduced. Once Logan's heartbeat is made to join in with the three other patients, his sprite and heartbeat line will move back onto the screen. This is an entirely visual change and does not affect gameplay from prior versions.
