Actual (spoiler) in the DM4 trailer, it revealed that Gru is actually scared of elders, revealed that he was the elder, not Gru when brother was born, it would be revealed that brother was the elder, not Gru

"Gru's character actual symbolizes the human spirit, he wants to keep pressing on, but his crippling fear of elders prevents him from making it too far in life" - Kyle Balda, creator of DM2
