I'm kinda conflicted when it comes to Ed. On one hand, sure, the old man's getting ballsy, thinking that he can just watch Lena change into her uniform in front of him, not caring about whether or not he makes Lena uncomfortable.
On the other hand, I don't really think that he's so much of a creep, but rather.... clueless. Just like Perry can sometimes say the dumbest shit in front of girls, I think Ed just doesn't think that his behavior is wrong, and I doubt there's hidden agenda to get into Lena's panties. I mean, it could be, but I think he's honest. In some way, I pity him. His wife is not well, and probably can't really be active in bed in her age, and all he can do is probably watch some porn and wank. Well, maybe on her best days Molly can wank for him, but not much else. So, as long as he doesn't overstep the boundaries too much and doesn't try anything funny with Lena, I say, let the old man live a little. Let him have his fun enjoying Lena's Peoplesgram and ogle Lena's body in her lingerie. Hell, I think his wife probably encouraged him to post his comment and compliment Lena, as Ed said, to make her feel better. At this point anything's possible. Time will tell, I guess. Everyone will show their true colors sooner or later.
