Many shippers claim the way that Clint talks to her and the way Natasha immediately helps once she's heard that Clint has been "comprimised" are signals of their love. Loki, the villian, also appears to take interest in their relationship, saying "Is this love, Agent Romanoff?"

Although Natasha denies it, many shippers say that Natasha is in denial. Also shippers have noticed that Natasha is wearing an arrow necklace in "Captain America, the Winter Soldier".
