Panel 1: We find ourselves in the kitchen watching Elly tell Liz that she's ready to take her shopping.
Panel 2: Liz introduces conflict and rejects all of the love in Elly's great big heart by wanting to go alone because she 'knows' what she needs. Elly asks 'What about clothes?'
Panel 3: Elly wants her to buy clothes that are practical (pronounced "androgynous looking"), sensible (pronounced "suitable for an eight year old") and that won't wear out (so that Elly doesn't have to buy clothes in bulk).
Panel 4: Liz thought-bubbles that this is why she wants to shop by herself.
Summary: She also doesn't want what eventually happens to April to happen to her and have Elly make a damned scene about what she wants to wear.
