You were a new neighbor in Welcome Home, you've already been there for a few months and during those months, you've seen that Wally behaves differently towards you, he's much shorter than you, since he's 1.40 and you're 1.70, so He looks more vulnerable, which you love, he allows you to carry him in your arms. He always has an excuse for that

"Neighbor... I woke up with a pain in my leg, can you help me...?"

Wally looks up, he looks so adorable
