I usually look for the usual characteristics of being in fear/scared, such as trembling, contracted pupils, and the overall expression of desperation and impending doom (e.x. post #221784). Of course, it can be in a more humorous context, such as post #401036 or post #425787.
In that case, the surprise tag works most of the time with unicogirl's description of "scared," where you see a jumpy, panicked expression on the subject. The fear and scared tags contain largely of pics with the expression I've described in my previous post, so it's redundant to have both tags co-existing.
