No one was to blame... I think.

Lupin didn't actually *have* the potion.  Isn't that why Snape 
stopped in Lupin's office and saw the Marauder's Map?  To deliver the 
wolfsbane?  I don't see why Snape would merely stop in to see if 
Lupin drank it, since Snape isn't very fond of Remus and also would 
have no reason to suspect that he had forgotten to drink it.  So, 
couldn't it be that Remus saw Peter's name on the map, but couldn't 
wait around for Snape to show up because there was the chance that at 
that *very* moment, Harry and company were in mortal danger?  


Geoff:
"'If you haven't been helping him, he (Harry) said, with a furious 
glanve at Black, 'how did you know he was here?'
'The map -' said Lupin. 'The Marauder's Map. I was in my office 
examining it -'
'You know how to work it?' Harry said suspiciously.
'Of course I know how to work it,' said Lupin, waving his hand 
impatiently. 'I helped write it.....

....'The important thing is, I was watching it carefully this evening 
because I had an idea that you, Ron and Hermione might try and sneak 
out of the castle....'

.....'You might have been wearing your father's old Cloak, Harry -'
'How d'you know aboutthe Cloak?'
'The number of times I saw James disappearing under it... ' said 
Lupin, waving an impatient hand again. 'The point is, even if you're 
wearing an Invisibility Cloak, you show up on the Marauder's Map. I 
watched you cross the grounds and enter Hagrid's hut. Twenty minutes 
later, you left Hagrid and set off back towards the castle. But you 
were now accompanied by somebody else.'
'What?' said Harry. 'No, we weren't.'
'*I couldn't believe my eyes*, said Lupin [my emphasis], still pacing 
and ignoring Harry's interruption, 'I thought the map must be 
malfunctioning. How could he be with you?'
'No one was with us!' said Harry.
'And then I saw another dot, moving fast towards you, labelled Sirius 
Black... I saw him collide with you. I watched as he pulled two of 
you into the Whomping Willow -'
'One of us!' said Ron angrily.
'No, Ron, two of you.'"

"Snape was slightly breathless but his face was full of suppressed 
triumph. 'You're wondering, perhaps, how I knew you were here?' he 
said, his eyes glittering. 'I've just been to your office, Lupin. You 
forgot to take your Potion tonight so I took a gobletful along. And 
very lucky I did... lucky for me, I mean. Lying on your desk was a 
certain map. One glance at it told me all I needed to know....'"

(POA "The Servant of Lord Voldemort" p.263 UK edition)

Does look a bit as if Remus was so gobsmacked by what he saw that he 
took off without thinking everything through....
