Owen was looking at Jack. "Will do, Just keep watch over him and let me know if hes getting worse." He headed off and goes to speak to Ianto. "Ianto can you try call Arwen?" explains what is going on.
"Oh no, but yes I'll call" Ianto muttered. He goes and grabs the phone and called Arwen, waits for her to answer.
