Tony is getting kind of suspicious because recently Nat and Bucky have been laughing at smiling at their phones more often.

There's two possibilities:
1. they're dating
2. they're both talking to bucky's new friend that gave him that pie a couple weeks ago

So being the privacy respecting person he is he hacks into their phones.
No biggie.

He is shocked to find that they've been texting this y/n, and he's not entirely sure that y/n is not a threat; so he's stealing caps job for a second and calling all avengers (minus Nat and Bucky) to get to the bottom of this.

How? You might be wondering.

Well he's going to use a group chat compromised of the Avengers, this should intimidate y/n, right?
