That’s one of the first times they used the same name for a person we never see.
Ward calls Dorothea Dunlap to get Eddie a date. Later or earlier Wally comes home from school to say Dorothea Dunlap got hysterical in math class. They took her to the infirmary but I don't know the episode. They use the name Dunlap a few times.

Dorothea Dunlap is evidently the Angela Valentine of Mayfield High.

We don't learn anything about her like we do about Angela. Things like eleventh toes, barfing in the cloak room, wearing a Jackie Kennedy wig, losing her retainer on the playground, suggesting the baby pic contest, etc.

Didn’t she faint at lunch and Eddie ate her ice cream as well?

That could be what happened to Ms. Dunlap. You’re right Beaver’s Poem was just on and she did faint and Eddie ate her ice cream. I think in another episode some girl did get hysterical and they took her away. Maybe soon they will show it. I think it might be in the new house.

I think it was in the new house, much later. Wally had just come home from school, and June asked him what happened that day.

I think also Beaver was supposed to kiss Angela “Valentime” and got sick didn’t go to school for 2 days.

"Valentime" was Beaver-speak, along with 'tricity, constellation prize, etc.
