spider & minion

Observation - spider & minion. Description: to the left of the 1st picture there's a second tiny pale spider between 1-2 mil, several of these were running quickly around the web and there are egg cases. Are they young or are they Oonops pulcher, which would make the large one Amaurobius fenestrali

to the left of the 1st picture there's a second tiny pale spider between 1-2 mil, several of these were running quickly around the web and there are egg cases. Are they young or are they Oonops pulcher, which would make the large one Amaurobius fenestralis, an altogether over-ambitious ID, I think, but an intriguing relationship described in the Collins Spider book (Roberts), Any suggestion for either or both welcome
