The bulk update request #3485 is pending approval.
create alias surprised_look (621) -> surprised_expression (15047)
create alias surprised_face (1053) -> surprised_expression (15047)
create implication surprised_expression (15047) -> surprise (40866)
Reason: We don't need three tags for the same expression. Out of all three tags for the facial expression, surprised_expression is by far the most used, so suggesting aliasing the others to that.
Judging by the way it is being used + the fact that a character/situation/etc can have 'surprise' as a concept without a character making a surprised face (or even with a deliberately contrasting expression)... Keeping both surprise and also surprised_expression seems valid enough. It does seem like it should be implicated though.
