Listening to Epic on Shuffle thought: There's this line on Little Wolf sang by Athena.
and I thought "Yeah, but that won't help him during battle. If anything, it'll make things worse." And that's when I realised, that's the exact thing Athena thought of in Warrior Of The Mind. And she saw the consequences it had on Odysseus (because, let's be real, she would have supported the Monster mentality at first. At least more than the Open Arms one). She realised she shouldn't stop people from being sympathetic or optimistic. She would use that second chance she has as much as she can with Telemachus. She wouldn't screw up again. I'll take that as proof that a) She has genuinely learned from her mistakes and b) kept an eye on Ody for a lot before Love In Paradise and saw exactly what her advice to be cold made of her friend.
Remember when I said I'll make a following post? Well, it's earlier than I thought. Lyric in question from We'll Be Fine:
I'm interpreting that as "This dude decided to go monster mode and I don't like that." So, if Athena hadn't kept an eye on him, an actual eye on him, she wouldn't have known. Last time she appeared, she was yelling at him for not being cold, for not killing the Cyclops and doxxing himself (fight me all you want, but that wouldn't have happened had Odysseus not been grieving Polites). She couldn't have known he took hers and Poseidon's advice to heart. That is, unless she still kept an eye on him before Love In Paradise. I don't whether or not it's confirmed she was keeping an eye on him, but yes, she was.
