This answer depends on which thing you mean b/c it’s either A) how do i think they’d work it out as characters or B) how do i think they’ll work it out on the show. 

the latter? I don’t think we’ll get much, i think, personally, that Eric is gonna try and stay out of the field from now on, personally. Which is a choice i’d like, a lot, if only because this show can at times be irritating at how blaze it is towards death counts. Remember in s1 where the team killed 4 people in an episode and they made a comment about that being a lot to deal with??? Imagine them caring nowadays. lol. 

But yes, i would personally like if Eric decided that no, it wasn’t for him, and they drove home what they touched on in the episode with Sam, that not being able to deal with that is fine, but you have to know whether you can or can’t, because there’s no middle ground. 

Like, as far as what i think we’re gonna get, and that i’d prefer, i’d pick that. I mean, when Nell got her first kill, she was immediately put into a situation wherein she had a choice, sit back and do nothing or help save somebody she cares about, and it obviously told her that yeah, she actually could take the toll, and in honesty, i feel like even if Eric did back out of field work, if it came between the choice of saving somebody he loves (or anybody really) he’d take the shot, which i actually think might be part of what’s bothering him about it anyway. 

so yeah, i imagine we’ll get that. Him backing out unless it is absolutely necessary for him to do it. 

But, as the for former, how i think they’d deal as characters? I think they’d eventually get to the point where Nell confronts him on the fact that he’s off, and then it’d all come spilling out? And like, following from my theory as to why he hasn’t confided in her, i think it’s probably a miscalculation that Nell wouldn’t understand any post-shooting trauma going on? Because like, we know Eric was worried that she went MIA after she shot that dude, he knows she didn’t take it well even if he didn’t see it b/c nell has /never/ done anything like that before, so i feel like Nell would completely understand?

I also think her perspective on it would help her know how to help him, she’s been there, she knows platitudes would probably be crap, and that he has to decide for himself and that it’ll probably hurt (like, we had post shooting conversations with Nate and Sam, and they were consistent, both of them were firm and truthful, but didn’t pull punches about it, Nell and Eric were given honesty, even if maybe it wasn’t what they wanted or expected to hear, Nell knowing that, having recently been through it and now worked through, will have good perspective on it.

 Which is basically that she knows it takes time, and it’s traumatising, and she will give him what he needs to work it out and not push him, which i think is the type of thing that could appear as distance, but also, any hovering wouldn’t be helpful to them or their relationship, either. 

I think he’d get through it, maybe he’d decide to go in the field again or maybe not, but he’ll get there, and Nell will be there. It’s not idea for them, but i do think their similar situations will help rather than hinder. Eventually he /is/ gonna get through the emotional roil, and it will be less confusing, and i think Nell would probably apologise for an obviously Adrenalin fueled poor timing to start making out with him thing. 

It was poor timing and pretty obvious her inhibitions were totally down and she acted on something she’d been thinking about but hadn’t gotten the courage to do, and i think she’d feel bad, so i think she’d apologise, and in that cute little neric fantasy land of my brain, he’d make it absolutely clear anything with her he’s never regretted, and it’d make it easier for him to separate the two things as well, now he’s made it clear to her, you know??
