I think he may have changed a little bit, but in a good way. He's there for Sydney more than he was in the first season. He seems happier to me, but he still has the same edge to him- like he could kill someone with one look. Anyway, he's till the same old Jack to me
Yes, and no. He's more open about his feelings towards Sydney, and he's become much more of a loving father, finally understanding his duty. Other than that, he's stayed the same, which I love about him
