Marriage counselor would definitely be some sort of chocolate egg because he's repeatedly expressed his love for chocolate (and his horror that we give our daughter vanilla ice cream rather than chocolate!) But not a Cadbury Cream Egg, because those are gross. Maybe a Mary Sue vanilla cream Easter egg. Very sweet on the inside. And the chocolate on the outside would be the same shade as his deep brown eyes. (Actually, I probably picture him more as a chocolate bunny, but you asked about eggs, so...)

For T, hm...I feel like she should be an elegantly decorated Easter egg, because she dresses very well. It would look like an Easter egg on the outside, and there would be a very thick shell to get through, but on the inside, once you take enough time to get there, she's very sweet. So...a candy egg hiding inside a fancy Easter egg shell?
