What Really Happened on "Night Train"

"She'll be coming 'round the mountain when she comes.  She'll be coming
'round the mountain--" Ellison warbled in fairly good voice as the
paramedics took the stretcher off the train.

"Okay, Sandburg.  Explain what happened to Ellison this time?" Simon
growled.

"You know that he had a bad cold before we left on this crazy trip."

"What's a little cold got to do with it?"

"Nothing is little when it comes to a Sentinel, Simon.  He wouldn't listen
to me and use a natural remedy.  He knows that we haven't tested his
reactions to over the counter medications."  Blair watched as they loaded
Jim in the ambulance.  Simon would drive Blair to the hospital.

"She'll be riding six white horses..."  Jim's voice was finally silenced
when the ambulance doors closed.

"What did he do?"

"He took a double dose of SenQyl"

"Shit.  A normal dose of that stuff will put a person to sleep.  What
happened?"

"He started hallucinating.  He swore that there were people on the train
sent to kill Wilson.  Then he said that Wilson was engineering a break.
He tried to jump off the train.  He saw a doctor who treated him at
Cascade General and thought he was one of the conspirators.  We had to
handcuff him to Isabel and radio ahead for paramedics to meet the train."

"That doesn't explain the singing."

"I haven't quite figured it out.  I think it has something to do with
Isabel Kane and the train ride through the mountains."

"Either way, kid.  You and I have a great blackmail story."
