Then I guess Dylan and conversing with the others, he'd know about Guy. If he pays special attention to ladies, he might have known Marly but Marly is sort of... too young. xD Plus, the whole punishment of the Auror trainees? He remembers that.
Meredith would be nice to Marly! Well, Mere's love is probably not known that much. It's one of those random-fact bits that doesn't crop up unless memes of "List 10 random facts about yourself!" are done. Plus, she's not going to realize yet that her love for Muggle Studies is so important, she can go on and study further. xD She would hit on Guy too because she's single and has a built-in guy radar like myself. And she goes "PFFT" to Doyle. xD
For the mod, I give you nakedwithhisarseshowing!Hugh.
