Given what we've seen of Faye's other relationships, it isn't surprising that she feels a little overwhelmed. After all, her time with Sven wasn't even really a relationship (although, in hindsight, Sven clearly wishes that it had been) and Angus reacted to the hard questions by attempting to deflect through humour, possibly because he wasn't any more keen than Faye was to confront them. So, yeah, that sudden down after the high is to be expected.
There is a lot being said in the body language here. Faye (in panel 1) and Bubbles (in panel 2) both adopt defensive postures. That said, I do like how they stay together and notice how Faye's body posture changes: She's stark naked and yet doesn't feel any need to protect herself from Bubbles' gaze. Bubbles, meanwhile, shows her reliance on Faye by moving very close to her, possibly into physical contact. The fact that their subconscious (such as it is in Bubbles' case) are so at ease with each other is, IMO, a very good portent for the future of their relationship. It's worth noting that Faye was very nervous about being seen naked by Sven and even with Angus she got dressed the moment she was out of bed; she doesn't have that problem with Bubbles.
Personally, I've got a feeling that this conversation will end with a hug and one of them saying something like this: "I can't make any promises but, as long as it is anything to do with me, we're going to be alright."
