I try to do a sense motive to see if the guy is lying about the bliss.

SENSE MOTIVE [one-action]
CONCENTRATE SECRET
You try to tell whether a creature’s behavior is abnormal.
Choose one creature, and assess it for odd body language,
signs of nervousness, and other indicators that it might be
trying to deceive someone. The GM attempts a single secret
Perception check for you and compares the result to the
Deception DC of the creature, the DC of a spell affecting the
creature’s mental state, or another appropriate DC determined
by the GM. You typically can’t try to Sense the Motive of the
same creature again until the situation changes significantly.
Critical Success You determine the creature’s true intentions
and get a solid idea of any mental magic affecting it.
Success You can tell whether the creature is behaving normally,
but you don’t know its exact intentions or what magic might
be affecting it.
Failure You detect what a deceptive creature wants you to
believe. If they’re not being deceptive, you believe they’re
behaving normally.
Critical Failure You get a false sense of the creature’s intentions.
