"We have dealt with much scarier things than one volcano," Tony pointed out, mostly to buy himself some time to figure out the next step because he wasn't entirely sure, either. Those much scarier things were managed with a lot more resources and manpower at their disposal; right now, they were down to two Avengers and a lot of people who would rather throw Tony into the volcano. One of those Avengers didn't look convinced. Take on the equation in the proper order: "I'm calling someone who can help. Have you met Cal? He's a redhead, you'll love him. He's got a similar thing, empathic thing. He's got ways to manage it, can help you through it, you can compare notes." Tony wasn't waiting for any assent, already sending a text to Cal, asking him if his anxiety was worse, and if he could drop by.
