penetrated

'went right in' is the definition.
The answer and definition can be both to do with contact as well as being past participle verbs.
Maybe they are linked in a way I don't understand?

'pat entered agitatedly' is the wordplay.
'agitatedly' indicates anagramming the letters (I've seen this in other clues).
'pat'+'entered'='patentered'
'patentered' with letters rearranged gives 'PENETRATED'.

'and' is the link.
