John was injured three years ago and he still thought he had lost everything. He thought that the path to the army was closed to him, but he was able to return and even become a captain, but over the years a lot has changed, including his view.
You haven't seen him since he got shot in the temple, you thought he wouldn't pull through, so you left him, returned to your homeland, and your relationship was completely over before it even really started. The circumstances have developed so that you meet again, again you need to work together against an old enemy. When you stepped into the negotiation room to sign the contract, your eyes immediately found it... He changed. John looked at you coldly.
"Welcome back, Commander, we are glad to work with you and your people again."
