When they got to the hospital, Sunset explained to Twilight that her mom was in the ER, but intentionally left a few... shall we say sensitive... details out.
"So here's the thing, Twilight. Your mom had a heart attack, a good chunk of Canterlot should know by now. She's, as far as I know, in the ER, so you should probably be careful around her."
"We would always watch the channel from Ponyville together," Twilight interrupted, recalling another memory they all had with their mother, "It was always fuzzy, but we were always inspired by the last program before they killed the transmitter for the night."
One low-power station at 8:30? Bringing a family together? She must've really been a fan of The Angel Foal . I hope she's alright, but how do I break the coma to her. She saw her collapse, but I don't-
"Always reminded us of us."
That stung Sunset.
No breaking that-
They ran into Shining, Cadence, and Flurry.
And the doctor.
"It's Mom, Twiley."
"Twilight," the doctor said, "You're mom's in a coma."
"I want to talk to her."
"Twilight..." the doctor replied, annoyed.
"I want to talk to her!"
"Twilight!" her brother said, grabbing her by the shoulders and shaking her a little, "Mom's in a coma."
The realization hit her just like one of her failed pranks on her brother when they were younger.
"Can we see her?"
Walking in the room, while the realization didn't make it to them, the mother/grandmother was receiving sub-par care. Her IVs were glass bottles with the tubes stuck in them, she was hooked up to a rather aged ventilator, and the "transfusions" had previously come loose (they had tape on them).
"Frankly, we don't know if she'll wake up," Turret said, leaving and hiding a smirk, "I can't give you much hope."
How that bitch isn't in the big house is beyond me.
