Sunny: Captain America's Daughter

Ever since Steve was discharged from the hospital after the whole Winter Soldier ordeal, the Avengers began to notice that something was off with the Super Soldier: he would keep his shield on twenty-four seven, and attached to him at all times; no matter where he was. The Avengers first believed that this was because Steve was adding an extra precaution, but when Thor went to the bathroom and walked into Steve bathing his shield with rubber duckies surrounding the bathtub as if he was performing a ritual, they knew something must be wrong with Steve. Along with the fact that when Natasha walked into Steve's room to talk about god knows what, she came across the 100 year old virgin singing Twinkle Twinkle Little Star" and "Ba Ba Black Sheep" while the shield was "dressed" in a robe covered in, well, tiny versions of itself and tucked under a purple blanket.

The Avengers finally came to a conclusion: Steve Rogers, the Star Spangled Man with a Plan, was going mentally insane, and needed therapy.
