Argos knew his ability to relate to humans was, if anything, slightly worse than his ability to relate with his fellow sheep.  More to the point, while he found other sheep too simple minded, too eager to follow the rest of the herd, his problem with humans seemed to be that, quite simply put, they were too complex.  He had a limited grasp on their communication, as well as their culture, but there seemed to be many nuances he was far from grasping.  This tended to leave him feeling a tad distanced from them.  More over, it also meant that, while he cared deeply about his "owners" (as they seemed to view themselves), he didn't always entirely understand what was going on with them.  

But... when Argos heard the screaming, he could only figure that it meant the mistress of the house was in pain, and that called for attention.  The woman, Mary, as the other humans called her, had always been kind to him.  Furthermore, for the past couple seasons, when Mary got close, he'd been able to hear a second heartbeat accompanying her own.  Coupled with the bulge in her stomach, this presumably meant she was with child.  And if she was with child, that would mean she should be watched out for all the more.  

Argos stopped to listen.  He wanted to make absolutely sure he didn't cause any additional injury with his upcoming action.  That meant figuring out exactly where everyone was located.  The screaming continued.  Argos knew there were others with her, but they didn't seem to be hostile.  One of them was Eugene, Mary's apparent mate.  There were several others with them as well, including a male who seemed to be reminding Mary to breathe.  Argos briefly wondered if it was actually possible for a human to forget to breathe.  Perhaps under the circumstances...

At any rate, Argos had determined the relevant information: The noises were coming from an adjacent room, behind a wall... Mary and the others would be safe.  

Argos took a step back.  Then he charged up the front steps, ran across the front porch and, with remarkable ease, reduced the front door to splinters.  He ran down the front hall, knocking pictures off the wall and toppling furniture.  He then turned around the corner, and...

... Sure enough, there was Mary, surrounded by the other humans.  She didn't seem to be injured, although she was laying on her back with her legs splayed out at an odd angle.  "That thing shouldn't be here!" someone protested.  
"He's fi-ARGH!" Mary responded.  
"He's fine," Eugene clarified.  

A few minutes passed as Argos tried to figure out what he was looking at.  Then it dawned on him:  This was human childbirth.  The achievement of this deduction was somewhat belittled, however, by the fact that it was shortly thereafter confirmed when the baby arrived.  

"It's a girl," a familiar male voice announced.  
"Diana," Mary remarked.  
"What?" Eugene responded, confused.  
"We agreed the baby wouldn't be named until after it was born, but I didn't say I'd wait a second longer." Mary explained.  
Eugene paused for a second.  "Ok..." he responded, slowly, "I'm just a little surprised you're this on the ball... why Diana?"  he asked.  
"I dunno," Mary responded, "It just came to me.  Cut the cord..."  

Argos kept his distance.  He knew to give new mothers their space.  But he had an odd sensation with the child's birth.  It wasn't an entirely new sensation, he had felt something similar with the birth of baby lambs in the past, but there was something slightly different this time.  Argos couldn't quite figure it out, but somehow he knew he wouldn't be quite so lonely now...
