"Let's see vhat I can do."

Schneep managed to sit up and swing his legs over the side of his bed despite Chase's and Doctor Iplier's protests, the German determined to help Seán after JJ recounted what had happened with Marvin.

"Doc, we can handle it. We don't know what's wrong with him anyway, so it could be nothing." Chase argued, Schneep standing up before looking at the male.

"Or it could be something that could make him become like Marvin. I am not taking zhat risk." Schneep countered as he limped towards Seán's room, JJ and Chase exchanging a look before they followed him.

"Wake up, Robbie miss you." Robbie mumbled with a soft whine as he curled up on the end of Seán's bed, his head nuzzling Seán's blanketed feet.

"Since ve don't know vhat is wrong, I'll have to do a series of tests." Schneep murmured thoughtfully to himself.

"JJ, did you bring the syringe like I asked?" Schneep questioned the dapper, JJ nodding as he handed Schneep the empty syringe.

"I need my space vhile I vork, I vill call you in if I require any help." Schneep told Chase and JJ, Chase opening his mouth to protest.

"Don't. Just....don't." Schneep cut him off, Chase closing his mouth with a frown as he left the room with JJ, Robbie reluctantly trudging after them.

"Let's start vith a chest x-ray." Schneep decided, carefully rolling Seán in a wheelchair using his uninsured arm before taking him to the x-ray room.

"Hmm...no pneumothorax, no chronic bronchitis, no sarcoidosis. Good, very good." Schneep sighed in relief as he looked over the test results.

"Okay, pulmonary angiogram is next." Schneep told Seán even though the Irishman was unconscious, moving him back to his room.

"Zhat is vorrisome." Schneep commented as he reviewed the results, nervously chewing on his lower lip.

Deep vein thrombosis, blood clots, and pulmonary embolism showed up as positive on the test.

"It's fine, I can fix zhis, I-I can fix zhis." Schneep stammered, pulling at his hair with his hands.

"Let's try a brain PET scan, zhat should give me a better idea of vhat Jack has." Schneep sighed in exasperation.

As Seán's brain was scanned, Schneep felt his face drain of color as he looked at the screen, shaking his head in disbelief.

"Nervous breakdown, chronic stress, dementia, and Parkinson's disease...I've never seen anything attack zhe body like zhis." Schneep whispered in disbelief, pulling Seán out of the scan machine.

"Fuck, my eye itches...no matter, have to focus on Jack." Schneep growled, rubbing his right eye with a scowl.

"Chase, JJ, get over here!" Schneep shouted down the hall as he brought Seán back to his room, laying the Irishman in bed as JJ and Chase entered.

"Antidepressants, ve need antidepressants." Schneep changed as he searched through his cabinets, helping Seán swallow a couple of pills.

"Something is tearing him apart from the inside at an incredibly fast rate, I don't know if I can save him." Schneep admitted as he turned to face the two.

"Doc-"

Chase broke off as Seán let out a pained cry in his sleep, his heart monitor spiking as the Irishman arched his back off of the bed.

"Jack!" Schneep cried, Seán coughing for air as he thrashed around while still unconscious.

"Stay vith me buddy." Schneep pleaded as he placed an oxygen mask over Seán's mouth, Chase and JJ making sure to stay out of his way as he worked.

"His systems are failing, I..." Schneep trailed off as Seán abruptly fell still, his heart monitor flat lining.

"Jack no!" Schneep sobbed as he pounded a fist on the frame of the bed, the stitch in his side popping loose to reopen his wound.

JJ rubbed the German's back in soothing circles as he looked away from Seán's body, tears glistening in his eyes as his body shook with silent cries.

"Oh my god." Chase murmured softly, his voice tinged with remorse as he stepped forward towards the Irishman.

"Gah!" Schneep wheezed as Seán's hand wrapped around his throat, the Irishman opening his eyes to reveal pitch black eyes.

"Jack stop!" Chase yelled as Seán sat up, lifting Schneep into the air while pushing Chase away from him, JJ staggering back in surprise.

"I am in control!" Seán, or whoever he had become, snarled as he stood up, Schneep weakly using his uninjured arm to swing at Seán.

Seán chuckled coldly as he let Schneep go, the German collapsing on the ground gasping for breath as Chase darted to his side.

"This world is mine, these people are mine. I've already won!" Seán exclaimed as he gestured around him, grabbing a knife off of Schneep's tray of surgical tools.

"Say goodbye." Seán smirked as he slit his own throat, blood trailing down the front of his shirt as he abruptly disappeared.

"Doc? Doc!" Chase shouted frantically, the German unconscious in Chase's arms with blood from the reopened wound staining his side.

JJ knelt by Chase with his notepad in hand, his expression grim as Chase read the words the mute had written.

It's up to us to stop Marvin and find out what happened to Seán. We need to know what's beneath the mask.
