Pippin:
Huggybunny my foot. But since Jen asked for explanations 
other than  EverSoEvil!Lupin, I'll just point out that 
Sirius's suspicion of his old friend isn't the only thing
besides legilimency/occlumency that needs explaining.
In no particular order:

Why does Lupin seem unaffected by the dementor on the 
train?
What was Lupin doing for twelve years between GH and
Book Three?
Why is he afraid of  Trelawney?
What's so funny about a cockroach?
Is his boggart really a full moon or does the "silvery orb" 
represent something else?
Why is Lupin absent on Christmas day in PoA when
it shouldn't be full moon yet?
How predictable is the period of transformation?
If it's not predictable, how could the prank work?
Why did Snape think Lupin was in on the prank?
Why isn't Lupin in any of Harry's photos?
Why wasn't Lupin at Harry's christening?
What is Lupin doing for the Order?
Why does Lupin's case say "Professor R.
J. Lupin" in peeling gold letters, if he's never had
paid work?
When Lupin leapt between Harry and Malfoy at
the ministry battle, why didn't Malfoy curse him?
