Warning! Possible spoilers for Avengers 4 lies below!

Avengers: Infinity War may have wrapped filming this summer, but Marvel Studios isn't ready to go on vacation just yet. Production is now underway on Avengers 4, and a new set photo has plenty of fans worried about the fate of Tony Stark and Bruce Banner.

Thanks to Page Six, several pictures of the Avengers 4 set recently hit the Internet. The images caused a frenzy at first because they showed Pepper Potts smooching Tony with a glitzy engagement ring resting on her finger. However, attention is turning to a more inconspicuous photo within the set.

The picture, which can be seen here, shows an emotional moment between two MCU heavyweights. Mark Ruffalo is shown as Bruce Banner gives Tony Stark a hug. The former appears to have a pained expression that borders on bereft, and Bruce isn't the only one looking overwhelmed. If you look behind Tony, fans can see Pepper staring out-of-frame with a stricken look on her face.

There's little context for what this scene may involve, but the photo has fans thinking Tony's loved ones will be in for some bad news in 2019. Avengers 4 will pick up once Thanos makes himself known in Avengers: Infinity War. These set pictures suggest Tony and Bruce will make it out of the Mad Titan's introduction alive, but that isn't to say the pair will be safe for good. Thanos may still be a looming threat in Avengers 4, and Tony might lay himself on the line yet again to protect the Earth from its intergalactic foes.

Avengers: Infinity War premieres in theaters May 4, 2018. Avengers 4 is slated to hit theaters a year later in 2019.

As the Avengers and their allies have continued to protect the world from threats too large for any one hero to handle, a new danger has emerged from the cosmic shadows: Thanos. A despot of intergalactic infamy, his goal is to collect all six Infinity Stones, artifacts of unimaginable power, and use them to inflict his twisted will on all of reality. Everything the Avengers have fought for has led up to this moment - the fate of Earth and existence itself has never been more uncertain.
