Since Captain America: Civil War, Steve Rogers and Tony Stark have not exactly been on speaking terms with one another -- which is pretty understandable, all things considered. After all, the last time they were both in a room with one another, they did very nearly murder each other.

Of course, this is an ever-evolving cinematic universe we're dealing with here so, obviously, Cap and Iron Man's beef can't continue on forever -- but if you're expecting their upcoming joint-outing in Avengers: Infinity War to be a magic, problem-solving bullet, you might be disappointed as this week's Marvel Studios-published prequel comic, Infinity War: Prelude #1, elaborated.

Following the events of Civil War, as the dust finally began to settle, we saw Tony opening a mysterious package while helping rehabilitate an extremely injured War Machine. Inside was a burner phone and a note -- a promise that, despite all their differences, Steve was just a phone call away.

However, it doesn't seem like things will be that simple as Infinity War looms in the distance.

Perhaps more interesting than Tony's general reluctance to call is is apparent knowledge that something is coming -- which, we, as viewers, understand to be Thanos and the Black Order -- but the extent to which Tony himself has figured that out remains to be seen.

Still, knowing what he knows to whatever extent he knows it, Tony's inability to bite the bullet and give Captain America a call is every indication that the proverbial hatchet has yet to be buried between the two heroes, something which could have a ripple effect throughout the MCU as Infinity War finally lands. After all, trying to get the band back together while the Mad Titan literally comes knocking at your door is not exactly the best or most productive use of time. Not to mention the fact that Tony seems to be doubling down on the secret-keeping tactics that landed everyone in the Civil War mess in the first place.

Either way, it doesn't seem like Cap's phone is going to be ringing any time soon -- at least, not in these prequel stories, and as such, we probably shouldn't expect things to be hugs and handshakes when Team Cap and Team Iron Man finally reunite on the big screen.

Avengers: Infinity War is directed by Anthony and Joe Russo and stars, among others, Robert Downey Jr, Chris Evans, Scarlet Johansson, Chadwick Boseman, Elizabeth Olsen, and Josh Brolin. It is set to hit theaters on May 4.
