1. In comparison to the few shtreemed interactions we've seen Dave have with his horse, he was marginally more affectionate toward his daughter. She'd appear in his videos and he'd awkwardly put his arm around her and do what looked like some really...weird caressing on her shoulder or whatever. Like, normally if you had your arm around your SO, you might gently rub with a thumb our your finger-tips (or so I've heard, I'm on Kiwi Farms so I don't have any semblance of friends or a lover, or anything that would indicate I have a ROBUST life). Phil's caressing looked more like he was uncomfortably petting a dog that walked up to him while at a friend's house. Beyond that, though, there wasn't a great deal of anything physical between the two. With regards to their interactions on shtreems and videos, they appeared to have more natural discourse and banter that would indicate a higher level of comfort. She was totally dominating, and he would act like a little bitch when she'd heckle him ("It must be MY fault when the laundry gets done, and MY fault when there's delicious cooked meals..." *Awkward Phil laughter*). She showed him a great deal of affection and he maybe, if I'm being generous, reciprocated with 1/10 of that to her. And that 1/10 is still infinitely more than he's shown towards Khet. He tends to talk about his wife *thumbs toward door* more than he did Leanna because he keeps trying to give off the air of being a real mature married adult Italian-by-way-of-Poland.
2. He might have said SOMETHING about proposing/marrying Panda in passing earlier than it came up when it did....but any real discussion in earnest happened after she made her instasnap post and showed up on shtreem not-so-subtly flaunting the ring over his shoulder. Beyond that, he only used the alleged proposal AFTER the Panda went to a different zoo to mate to get pity-bux from his wheelchairs. I can't imagine him ACTUALLY ever planning to propose to her without her low-key nagging him about it.
