I hope he'll be OK. :/ I did tell him when he called to let me know if he got into trouble so I can talk with his team lead. I think he appreciated that but he sounded worried and scared despite how I apologised for the misinterpretation.

He said he'll ask for some IT tasks to be offloaded and I seriously hope his team lead agrees. Because that time sensitive task is getting critical and he really needs free time to do it. Or else I'm getting in trouble myself lol.
