This is expected to happen next week.
Yesterday, Justice David Collins and the jury of five men and seven women heard from the mother of three of the complainants.
The mother gave evidence that she considered Bell's behaviour with a fourth complainant to be "inappropriate" in the level of closeness he showed with her.
"It was very ... real hands on, real over-affectionate," she said.
"She always had to be sitting on his knee rather than sitting on the couch.
"There's affection and there's over-contact as far as I'm concerned."
On one occasion, the witness went to Bell's house, where he had the girl in his room with him. "I knocked on the door and he had a knife in the door," she said.
"He told me it was because [the girl] gets scared and thought people would come in the room."
Mr Steedman said Bell has denied such an incident.
Despite telling the court she had "concerns" about Bell's behaviour with the girl, as well as her own children, the witness said in a police statement last year she "just saw him as playful" and she hadn't been worried.
She told Mr Steedman she had been on medication when making the statement, and that was why she "didn't see it for what it was".
Bell's mother also gave evidence, saying she had once found pairs of "young girls' knickers" under Bell's mattress.
Mr Steedman suggested some of the complainants who would sleep in Bell's room when they came to stay might have pushed their underwear under the mattress themselves.
The witness agreed that could have happened.
The trial continues on Monday.
