Vetch seeds in sweet pea packet

So sorry - I have searched and searched but can’t find the post.
It was either Martin or JJB.
Apologies to one of you!
Anyway we both had some odd seedlings pop up in our sweet pea sowings that looked like vetch foliage.
Not even from same supplier - mine was cheapo from Lidl (incidentally, they have been fabulous!!)
Martin’s of JJB’s came from a “proper” seed merchant. 
I grew mine on in a three inch pot- didn’t bother to plant them out. Here they are …. Quite pretty and def not vetch!
How did yours do Martin or JJB????
