"Of course." Charles leans away slightly to look at Erik then. He completely understands. What happened to him as a child had been a traumatic event, and killing Shaw hadn't fixed that. Erik still has those nightmares. Sometimes Erik would wake up in the middle of the night covered in cold sweat, but Charles is always there to help calm him down, just as he's doing now, trying to keep his focus on the present, not on the past.

"We have all the time in the world. I'm not going anywhere." He rubs his thumb over Erik's cheek affectionately, and he presses a quick kiss to his lips before he reaches down to grab at the blanket that had slid off their lap, tugging it over Erik's shoulder to get him comfortable.

"Now, where was I..." Charles says as he picks up his book again, looking to read another few chapters before joining Erik for a nap. They've a few more hours before they're in Oxford and it'll be late afternoon by the time they get there. He wants to drop by the store to buy some basic toiletries before heading to the apartment, and then they'll need to open all the windows because no one's been there for months. He really hopes the place isn't a terrible mess. He can't remember if he'd bothered to clean up before he'd left in a hurry after meeting Moira.
